The family of Kevin McDaid, the Catholic man beaten to death by a loyalist mob in Coleraine, has complained that police failed to provide protection on the day of the killing.
Members of Mr McDaid's family have now lodged a complaint with the PSNI Ombudsman, saying they are concerned the police were involved in negotiations with loyalists on the day of the murder.
They say loyalists had threatened violence unless certain demands were met.
And while the PSNI Chief Constable Sir Hugh Orde has already referred the case to the Ombudsman, the McDaid family today claimed the Catholic community was not given adequate protection.
In a statement issued by the family's solicitors, they said they were further concerned that given the prior knowledge of the threat, 'neither we or our neighbours were properly protected by the police.'
Mr Orde said talks had been taking place between both communities, but no-one would dictate terms to the police.
Meanwhile, the PSNI is continuing to question a 33-year-old man about the murder of Mr McDaid.
The man is one of two arrested yesterday in connection with the murder investigation.
Last night, a 53-year-old was released on bail pending further inquiries.
Six men were charged yesterday with Mr McDaid's murder during a series of court appearances at Ballymena.
The suspects have denied the charge.
Mr McDaid, 49, was attacked on Sunday evening by up to 40 men who entered a mainly Catholic housing estate after Rangers beat rivals Celtic to the Scottish Premier League title.
