The family of the man mistakenly shot dead by police have made an official complaint about alleged misinformation circulated after the shooting.
The Menezes family say police should have corrected early reports
Jean Charles De Menezes' family are angry early reports suggested he had fled from anti-terror officers and was wearing a bulky jacket.
The Independent Police Complaints Commission has been asked to examine why police did not correct the claims.
The Stockwell Tube death came the day after the 21 July failed London bombs.
The 27-year-old electrician was shot seven times in the head by anti-terror officers after being mistaken for a suicide bomber.
The investigation comes after the Menezes family's lawyers wrote to the IPCC, which is also investigating the shooting.
Speaking at the end of their London visit, the Brazilian's relatives said Scotland Yard should have done more to dismiss misleading reports.
Harriet Wistrich, one of their solicitors, said: "We know Sir Ian Blair [Metropolitan Police commissioner] made a statement saying he [Mr Menezes] did not stop when challenged.
"There have been other pieces of information which went out into the media.
"This is something that happens again and again when people are killed by the police.
"It should not have been allowed to go on for so long."
An official complaint has also been lodged about the length of time it took for police to inform them of the 27-year-old's death.
The family say they were not informed of the shooting until 30 hours after it had taken place and that they had to go to the police station to find out what had happened.
At a press conference Mr Menezes' mother, Maria Otone da Silva, and two of his cousins repeated their call for the truth about his death and for the officers responsible to face charges.
His mother said: "I'm so sad about what has happened to my son but I feel the English people, everybody wants to have the truth.
"The police did the wrong job. Of course we have to have justice and the investigation but they did wrong and I hope we find the truth and that they go to prison."
