A 29-year-old man has been arrested at Heathrow Airport on suspicion of terrorism as he was about to board a flight to Saudi Arabia.

A home in west London is now being searched and the force said several electronic devices have been seized for analysis.

A police driver following a teenager who died after he came off his moped has told an inquest jury how he was "shocked to my core" when he saw the rider lying motionless in the road.
Two unmarked police cars were following 18-year-old Henry Hicks at the time of the accident in Islington, north London, on the evening of 19 December 2014.
The driver of one of the police vehicles, who cannot be named for legal reasons, told St Pancras Coroner's Court sitting at the Royal Courts of Justice today he had been following the teenager with the intention of pulling him over as he suspected he had been dealing in drugs.
But he said he had not been "in pursuit" of the rider, telling the jury and the senior coroner for Inner North London Mary Hassell: "In my heart I knew that he hadn't seen me.
"He gave me absolutely no indication that he was aware of me."
The PC, who gave his evidence screened from the public by a curtain, said when he turned into Wheelwright Street there was "no sign" of the teenager.
At first he could see that there was a "moped on the floor, but I couldn't see where the rider was at this time".
"As I got closer, I saw that the rider was lying on the floor in front of the car that was facing me. He was lying on his front and not moving."
The inquest continues.
A campaign has been launched for all water workers to be paid the living wage after a study found a "huge chasm" between the pay of bosses and other employees in the industry.
The Unison union said all water companies should follow the example of those in Yorkshire, Scotland and Northumberland and pay the £8.25-an-hour rate, and £9.40 in London.
Unison general secretary Dave Prentis said: "Water companies are making huge profits and paying their top executives massive salaries.
"They could easily afford to start paying their lowest-paid employees a proper living wage. This is the very least that workers in the water industry deserve.

London's new night Tube is set to be extended to a third line within weeks of being launched, according to sources.
The all-night service will start on 19 August on the Central and Victoria lines, after agreement was finally reached with unions.
It is understood the night Tube will be extended to the Jubilee Line from 2 September.
Finn Brennan, district organiser of the train drivers' union Aslef, said: "We welcome the hundreds of new jobs with decent conditions that were created by our action last year.
"We made sure it was brought in by agreement in a way that benefits existing staff and the new recruits."
The new service was originally due to start last autumn but was held up because no agreement was reached with unions. The night Tube will be extended to other lines later.

Ecuador's Foreign Minister Guillaume Long says there is concern about the health of Julian Assange, who has now been in London's Ecuadorian Embassy for four years.
He told Zeinab Badawi: "We are concerned about his health. He doesn't have access to good health care. We are very worried about this. After four years, there is a clear deterioration."
The Wikileaks founder sought refuge in the embassy in 2012 to avoid extradition to Sweden on charges of sexual assault, which he denies.
Mr Long said: "Ecuador is getting very fed up with this. It is an embassy under siege. You try making a phone call from the embassy and see if that works. It's probably one of the most spied on embassies in the world."
But he said there were no regrets about the decision to offer Mr Assange refuge.
The victims, aged 18 to 38, were assaulted in East Acton between January and March.

Serious questions will be asked over why helpless Ellie Butler was returned to the custody of her "appalling" parents just under a year before she died, a leading charity has said.
Ellie, six, was placed back in her parents' care in November 2012 after Family Court judge Mrs Justice Hogg ruled that her father Ben Butler had been the victim of a miscarriage of justice over a quashed conviction for shaking her as a baby.
In reality he was a violent thug and once she was in his care, Ellie suffered a series of injuries including a broken shoulder that was left untreated for a month before she died at her father's hands in late October 2013.
He and her mother Jennie Gray focused on hiding evidence instead of getting help for their daughter when she had been fatally injured.
An NSPCC spokesman said the judgment may have given Butler confidence to continue abusing Ellie.
"There is no doubt this put social workers on the back foot and possibly emboldened him to continue with his violent campaign against a helpless child.
Butler confronted social workers with aggression and black-hearted deception and even now appears unwilling to accept responsibility for his terrible actions.
"There will naturally be many serious questions about why and how this appalling couple were granted custody of their children, despite the alarming signs that should have raised red flags. But it's worryingly clear the child's voice was lost when it should have been the focus of attention."
The Museum of London has restored a 17th-century fire engine in preparation for its forthcoming exhibition, Fire! Fire!, commemorating the 350th anniversary of the Great Fire of London.
Originally built in London in the late 1670s by John Keeling, the only surviving part when the museum acquired the fire engine in 1928 was the central barrel and pump.
The restoration was modelled on a 19th-century photograph of the engine which showed it still intact with its undercarriage, wheels, tow bar and pumping arms.
Fire! Fire! runs from 23 July to 17 April2017 and will focus on life on the eve of the fire, the dramatic events that took place as the blaze burned through a quarter of the city in 1666, and how London recovered from the devastation.

February 2007: At six weeks old and in the sole care of her father, Ellie was found to be "suddenly soft and limp". Scans showed she had serious injuries.
June 2007: Ellie was placed in the care of her grandparents.
January 2008: The Family Court found that, on the balance of probability, Butler caused Ellie's injuries and Gray failed to protect her.
March 2009: Butler was convicted of grievous bodily harm and was sentenced to 18 months in prison. He had a history of offending and violence.
June 2010: His criminal conviction was quashed by the Court of Appeal on the basis of new medical evidence.

Six-year-old Ellie Butler died less than a year after she was returned to her parents.
Social services, police and the courts had all been involved in her care since shortly after she was born on 30 December 2006.
Jailing Ben Butler, Mr Justice Wilkie told him: "You are a self-absorbed, ill-tempered, violent and domineering man who, I am satisfied, regarded your children and your partner as trophies, having no role other than to fit in with your infantile and sentimentalised fantasy of family life with you as the patriarch whose every whim was to be responded to appropriately."
He told a sobbing Jennie Gray that she may have been "exceptionally naive and stupid" to believe Butler and take part in the cover-up.
Christine Davies CBE, independent chair of the Sutton Local Safeguarding Children Board, has expressed deep sadness at Ellie Butler's death.
In a statement she says: "Our thoughts and prayers go out to those who knew and loved her, particularly her maternal grandparents for the love and care they showed to her in the 5 years that she lived with them.
"The SCR found that this was an exceptionally unusual case. Ben Butler had previously been found guilty of Grievous Bodily Harm (GBH) on Ellie in 2007 and then had his conviction quashed at the Court of Appeal. His conviction for GBH on Ellie was quashed because it was considered to be no longer beyond reasonable doubt.
"This was on the basis of new expert medical evidence. This does not mean he did not injure Ellie.
"After Ben Butler’s conviction was quashed, Ellie’s mother, Jennie Gray, took their case to the Family Court to have the finding of fact, that Ben Butler was responsible for injuring Ellie, overturned.
"The Family Court Judge went much further than the Appeal Court ruling and stated that ‘any injury caused was purely accidental’, that Ben Butler should be exonerated and that he was a victim of a miscarriage of justice.
"The Family Court Judge went on to state that she did not attach any culpability to Ben Butler for the 2007 injury. The Family Court appointed an independent social work agency called Services for Children to assess and oversee Ellie and her younger sibling’s placement with their parents.
"Sutton Council strongly contested the decision made by the Family Court to have Ellie and her sibling placed with their parents. The SCR found that neither Sutton Council social workers nor staff from other LSCB agencies could have done anything more to save Ellie’s life. Sutton Council fought to keep Ellie in care and away from her parents but this was ultimately dismissed by the Family Court."
Jennie Gray is sentenced to a total of 42 months for perverting the course of justice and child cruelty
Ben Butler is given life with a 23 years minimum term.

During sentencing, the court heard that Jennie Gray only learned today that her mother died two months ago. Her father Neale Gray - didn't want to tell her.
Jennie Gray sobs uncontrollably in the dock as her barrister tells the court that she was handed a letter by police about her mother's death.
Mr Justice Wilkie says Ben Butler is a violent, ill tempered, domineering man who attacked Ellie with "lethal violence" and arranged the scene.
Ellie Butler's maternal grandparents described their utter devastation at her death, saying: "She was our shining light."
Grandmother Linda Gray died on the first day of the murder trial and her husband Neal was understood to be too ill to give evidence.
The couple had cared for Ellie after her father Ben Butler was accused of shaking her as a baby, but they were forced to hand her back 11 months before her death.
In a joint statement written ahead of the trial, they described how they struggled to come to terms with the "shock and horror" of her death.
They said: "Our lives have changed so dramatically due to the impact and shock and horror of this event that we struggle every day to deal with the reality of the death of our dear granddaughter Ellie. She was our shining light.
"Ellie was a very beautiful, bubbly and intelligent little girl who always had a smile on her face and even at such a young age she was nobody's fool. She was our life and she gave so much pleasure to us and our family too, how we all miss her."
Ellie Butler's absences from school and bruises should have been "a red flag" that she was being mistreated, a leading children's charity has said.
An NSPCC spokesman said: "This tragedy raises serious questions about why Ellie was returned to the man who would eventually kill her - questions which a serious case review must address.
"There were signs such as absences from school and bruising which should have acted as a red flag that Ellie was in danger.
"Despite this she was left at the mercy of Ben Butler, who has shown himself to be a violent, aggressive and manipulative man, more concerned with covering his tracks than seeking medical help for his daughter.
"He was aided in this sickening crime by his partner Jennie Gray, who has been revealed to be just as conniving, deceptive and duplicitous. There are obviously lessons to be learned from such a harrowing case."

The senior officer in the Ben Butler case has rubbished the defendant's claims of a police stitch-up, saying he was convicted of killing his daughter by "overwhelming evidence".
From the very first day, Detective Inspector Dave Reid said he was "suspicious" about the circumstances surrounding little Ellie's death because of the extent of her horrific injuries.
But it took another two and a half years of "painstaking" work - in the absence of any CCTV or reliable eyewitnesses - to bring the case against Butler, pictured above, to court.
The BBC's Gaetan Portal says the judge in the Ben Butler trial has indicated sentencing of him and his partner Jennie Gray, which is just beginning, could take up to an hour.
The Sutton Safeguarding Children Board has just issued this statement following the guilty verdicts in the Ben Butler trial:
The board is deeply saddened by the tragic death of Ellie Butler. Our thoughts and prayers remain with Ellie's extended family and friends for their enormous loss, particularly her grandparents who played such a positive role in her life. An independent serious case review has been carried out to consider the circumstances of Ellie's death.
After the guilty verdicts Ben Butler's lawyer Di Middleton asked for sentencing at the Old Bailey to be adjourned.
But Butler shouted out: "Di I want to be sentenced now. There is no need - you can sentence me now so I can fight in the appeal court and prove this wrong. I will fight forever to prove this wrong."
Mr Justice Wilkie adjourned sentence to 12:30.
Mrs Justice Hogg, who "exonerated" Ben Butler at the Family Court in 2011 retired earlier this year.
In some of her final words on the matter, she wrote: "It is seldom that I see a 'happy end' in public law proceedings. It is a joy for me to oversee the return of a child to her parents… the story does not end today. There is still work to be done."
The BBC has approached her for comment.
