The trial of Nicky Jacobs began at the Old Bailey on Monday of this week.
He is the seventh person to be charged with the murder of PC Keith Blakelock, who died during the 1985 Broadwater Farm riot in Tottenham.
Blakelock died after sustaining multiple stab wounds. Nicky denies the murder.
Opening the crown’s case, Richard Whittam QC told the jury that the evidence against Nicky has been obtained from witnesses who allege they took part in the attack.
Whittam said witnesses “have been provided with some degree of financial assistance by police” for their “willingness to give evidence and co-operation”.
He said payments were “subject to a strict authorisation procedure and are limited.”
Over 50 of Nicky’s friends and supporters protested outside the court on Monday of this week.
