Key witnesses in the trial of Nicky Jacobs for the murder of PC Keith Blakelock received perks from police including payments, a court has heard.
Nicky was 16 at the time of the murder in north London in 1985. He denies the charge.
The two men providing evidence against him allege they were part of a group who attacked Blakelock during the Broadwater Farm riots.
They have been granted immunity from prosecution in exchange for co-operating with Scotland Yard.
The trial at the Old Bailey heard how the men, known by the pseudonyms of John Brown and Rhodes Levin, had received £5,000 each.
Levin also had a flight from Spain paid for by the police, said Courtenay Griffiths QC, defending.
Griffiths cross examined Detective Superintendent John Sweeney, who has overseen the investigation.
He agreed when Griffiths asked if the MOT on Brown’s car had also been paid for by police.
The trial continues.
