The mother of murdered schoolgirl Toni-Ann Byfield has been taken to an immigration detention centre following attempts to deport her to Jamaica.
Roselyn Richards was taken off a plane at London Heathrow, which was bound for Jamaica, yesterday lunchtime with her two children.
Ms Richards, a Jamaican national, is understood to have been living in the London area and submitted a visa application to extend her stay in the UK two days after a deadline, according to a group supporting her.
She had wanted to remain in the country while the investigation continued into the death of her seven-year-old daughter in London in 2003.
Ms Richards last night claimed she feared she and her two sons would be killed if they returned to Jamaica because she had helped police investigating Toni-Ann's murder.
"I fear for my life and my kids' lives," she told Channel 4 News.
"If I was to go home right now, back to Jamaica, me and my two sons are going to end up like Toni- Ann, because people in Jamaica call me a police informer, they say I've given the police information."
She added: "I would like to know what's going on because my daughter died here, and it seems like after I've given the police what they wanted I am nothing to them." Toni-Ann, who had been in the care of Birmingham social services, was shot dead alongside her convicted drug dealer father, Bertram, aged 41, at his flat in Harlesden, northwest London. The investigation into their murders is still on-going. The hunt for the killers has spread to Jamaica.
London Mayor Ken Livingstone's policy adviser Lee Jasper said he had urged the Home Office to review the case.
"She has suffered enormously with the brutal slaying of her daughter and I think that the Government and the Immigration Service really ought to look again at this case, at this stage through the appeal, and grant this mother compassionate stay," he said.
Ms Richards' solicitor Andre Clovis said his client had claimed asylum in the UK because of fear for her safety if she returned to Jamaica.
Mr Clovis, from London law firm Christian Khan, said: "A member of her family has already been murdered for asking questions in relation to Toni-Ann's death. He was asking questions or challenging someone he believed may have been involved or associated with the killing. He was threatened and three days later found shot dead."
He added: "She's received death threats herself and she's communicated those concerns to the police but for whatever reason it doesn't appear to have been taken seriously."
The lawyer said they would be pushing for the Home Office to show "humanity in the case.
Deporting her would deny her the chance to attend her daughter's inquest - a date for which has yet to be fixed by the coroner - and see the killers brought to justice, he said.
A Home Office spokesman said they could not comment on individual cases.
But he added: "The removal of those who have no legal right to be in the UK is an essential part of a credible immigration system in which the public can have confidence."
