Three police officers have been charged in connection with the death of a man whose vigilante killer wrongly believed he was a paedophile.
Bijan Ebrahimi, 44, was beaten to death and his body set on fire by neighbour Lee James in Bristol on 14 July, 2013, amid false speculation he was a paedophile.
James, of Brislington, was later jailed for life for murder, while Stephen Norley, who lived next door, was jailed for four years for assisting an offender.
The Independent Police Complaints Commission submitted a file of evidence to the Crown Prosecution Service in October 2014.
The file considered how officers responded to events and contact from Mr Ebrahimi.
Now, the Crown Prosecution Service has announced three police constables and a police community support officer will be charged with misconduct in a public office.
PCs Kevin Duffy, Helen Harris and Leanne Winter, all of Avon and Somerset Constabulary, are to be charged with misconduct in public office.
It is alleged they failed to respond to allegations and calls for help from Mr Ebrahimi.
PCSO Andrew Passmore is also to be charged with misconduct in public office.
It is alleged he gave false information to the 999 operator that he was outside Mr Ebrahimi's home at an important time.
He will also be charged with perverting the course of justice for allegedly giving different accounts to the police murder investigation and the IPCC investigation.
The CPS said there was insufficient evidence to bring charges against a police emergency call taker and an emergency call supervisor.
Malcolm McHaffie, deputy head of special crime at the CPS, said: "The decision to prosecute was reached after careful consideration of the evidence and was taken in accordance with the Code for Crown Prosecutors."
All four individuals will appear at Bristol Magistrates' Court for a preliminary hearing on 14 January 2015.
A post-mortem examination found Mr Ebrahimi, an Iranian national, suffered "multiple heavy blows to the face and head" and died before he was set alight.
James and Norley were jailed at Bristol Crown Court in November last year after entering guilty pleas to murder and assisting an offender respectively.
The court heard Mr Ebrahimi was murdered three days after he had been arrested by police.
The arrest was made following complaints that he had been taking pictures of children outside his home.
During the fatal attack, father-of-four James, who believed his victim had been filming his children, repeatedly stamped on Mr Ebrahimi's head.
He told him "have some of that".
Father-of-two Norley, who worked for a fruit and vegetable wholesaler, helped James drag Mr Ebrahimi's body from the scene of the attack.
He then obtained white spirit to burn it, a court heard.
Speaking after the case, Mr Ebrahimi's sister Manizhah Moores said her brother suffered racial abuse while living in Bristol.
"We hope that nobody else ever has to witness an innocent disabled man being abused, taunted and tortured in the way that Bijan suffered," Mrs Moores said.
