Police could face misconduct proceedings over the way they dealt with a musician who died in custody, in the wake of a review published today.
Sean Rigg died in August 2008 while he was being held at Brixton police station.
The sister of Sean Rigg, who died while he was being held at Brixton police station in 2008, has welcomed a review which said the IPCC should look again at whether police officers should face misconduct proceedings for the way they dealt with Rigg.
She said: "It is the family's strong opinion that possible criminal offences should also be considered afresh."
"My family's pursuit of justice and our dignified determination to arrive at a truly clear picture of what happened," she added, "has hopefully contributed to real and positive change into the way the IPCC and all key agencies should fulfil their obligations, by law, into a death in custody."
IPCC chairwoman Dame Anne Owers said that Sean Rigg's family had shown "determination and dignity" over a long period. She added:
We are already taking a critical look at the way we investigate deaths in general and this specific review, and the lessons to be learnt from it, will play an important part in the way that we develop and change our approach.
A review of the way police dealt with Sean Rigg, who died while he was being held at Brixton police station, was set up by the IPCC to re-examine its own investigation into Mr Rigg's death.
The report found:
The review recommends that the IPCC reconsider the conduct of the police officers involved in the apprehension, restraint and detention of Mr Rigg, in relation to possible breaches of their duty of care, with a view to determining whether to bring misconduct proceedings.
The four officers did not check the name on the 'stolen' passport with police records that would have flagged Mr Rigg's mental health needs and could have alerted them to the fact that the person they were dealing with was actually Mr Rigg.
He was well-known to the police through repeated past contact with the police and mental health services.
