Three arrested on suspicion of supplying forged papers
Three men have been arrested by counter-terrorism officers on suspicion of supplying forged documents, the Metropolitan Police has said.
The three men, aged 28, 33 and 30, remain in custody at a police station in central London.
A search linked to these arrests has been carried out in the East Midlands, while searches at two addresses in London are ongoing, police said.
The men were arrested by the Met Police's counter-terrorism unit.
The latest arrests follow dawn raids in London on Thursday in which a 40-year-old man was arrested on suspicion of conspiracy to possess and supply fraudulent documents.
Stopped a car
He has now been bailed and told to return to a police station in January next year pending further inquiries, the Met Police said.
But a 33-year-old man, who was arrested on the same day on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism, remains in custody.
In his case, a warrant has been granted by the courts to allow the police to detain him until 11 December if necessary.
Police said that searches taking place at five residential addresses - four in south-east London and one in Stoke - in connection with Thursday's arrests had now finished.
A further two men, aged 33 and 43, were arrested in Dover last Sunday after Scotland Yard officers and Kent Police stopped a car going outbound at the port.
A 28-year-old man was arrested at the same port on Monday, and under the same operation, two men, aged 24 and 40, were also arrested in east London.
All five men remain in custody and warrants for their extended detention have been granted until 14 December.
Police said that searches linked to the arrests of these five men at residential addresses in London and two in north Wales had now been completed.
The terror threat level in the UK was raised from substantial to severe in August.
Fears of a terrorist attack on the UK have been heightened in the wake of the rise of Islamic State (IS), the extremist group that has taken over large swathes of Iraq and Syria.
