Hundreds of protesters have marched through central London calling for a public inquiry into the death of British reggae star Smiley Culture.
The singer, whose real name was David Emmanuel, died of a stab wound while police were searching his home.
His family was told he stabbed himself but the case has raised concerns about victims who die in police custody.
The Metropolitan police refused to comment on the case, but it says an investigation is being carried out by the Independent Police Complaints Commission.
