A further four Avon and Somerset police officers are being investigated over their dealings with a man who was murdered and set alight outside his Bristol home.
Iranian-born Bijan Ebrahimi was killed last July after neighbours wrongly accused him of being a paedophile.
The Independent Police Complaints Commission (IPCC) has today revealed it has issued a further four investigation notices to police officers and has carried out further criminal interviews with two officers and one PCSO.
Mr Ebrahimi, who lived alone in the Brislington area of Bristol, took photographs of those he accused of destroying the window boxes he tended outside his council-owned maisonnette.
Lee James and Stephen Norley, both 24, who lived near their victim, admitted their part in the attack last July.
James was sentenced to life with a minimum 18-year term, after pleading guilty to murder while Norley was given four years after admitting assisting his co-accused.
He turned to the police for help and phoned them on July 11. But instead Mr Ebrahimi was arrested on suspicion of a breach of the peace.
