Five police officers will learn later if they will be charged over a racist attack on a terror suspect.
Director of Public Prosecutions Keir Starmer is expected to announce whether anyone will face trial over the arrest of British Muslim Babar Ahmad.
Up to five Metropolitan Police officers could be prosecuted over an attack on the 36-year-old as he was held in Tooting, south London, in December 2003.
The officers, all members of the force's controversial territorial support group, have been accused of a "serious, gratuitous and prolonged" attack.
The Met paid £60,000 damages in March last year as lawyers for Commissioner Sir Paul Stephenson admitted Ahmad had been the victim of violence. Court documents revealed officers beat and grabbed him around the neck, pulled his testicles and mocked his Islamic faith.
Among the suspects is Pc Mark Jones, who was cleared last year of racially abusing two teenagers in a separate incident.
