A FORMER race relations adviser in Bradford has vowed to fight on after a police watchdog found the West Yorkshire force had not sought to undermine his credibility as a witness at a public inquiry following the Stephen Lawrence murder.

The Independent Police Complaints Commission (IPCC) began an investigation in July 2013 after documentary evidence from West Yorkshire Police suggested discreet inquiries were conducted into the background of Mohammed Amran before he appeared at the Macpherson Inquiry in Bradford in 1998.

Former Chief Constable Sir Norman Bettison was interviewed under criminal caution by the IPCC but denied ordering a report on Mr Amran, who was then a Commissioner for the Commission for Racial Equality.

Today, the IPCC announced it had found no evidence that the report was used to undermine Mr Amran's credibility.

But the watchdog said that the lack of a comprehensive audit trail and poor recollection from former police officers meant it was not possible to establish why the report was compiled or who ordered the background inquiries to be undertaken.

IPCC Commissioner Cindy Butts said: "This intelligence report was compiled in the run-up to an inquiry of significant national interest. The lack of available documentary evidence and clear recollections from former officers has been problematic for the investigation. It means there is no clear explanation as to why it was ordered or who requested it."

But she added: "There is no evidence of the report being used to undermine the witness’s credibility at the Macpherson Inquiry.

"West Yorkshire Police did not breach the national policies and procedures applicable at the time."

But Miss Butts said it would leave the witness with a number of unanswered questions.

But Mr Amran condemned the IPCC report as "wishy washy".

He said: "There is no substance to it and no justice in it. They have failed me and they have failed the community."

Mr Amran, who still lives in Bradford, said it was why a lot of communities did not have trust or confidence in the police, or organisations like the IPCC.

He added: "How can you not detect a trail of emails or correspondence? Who has destroyed or got rid of it? You cannot have an intelligence report and not be able to prove who has authorised it."

Mr Amran, who now carries out voluntary work and looks after his son who has leukaemia, said he was taking legal advice about the next step.

He said: "This is not the end of the matter. My legal team is looking at it and we may take action. We still want answers."

West Yorkshire Police Deputy Chief Constable John Robins said: "West Yorkshire Police has co-operated fully throughout the independent investigation carried out by the Independent Police Complaints Commission. We welcome the thoroughness of the report compiled and note the findings in this case."
