A 44-year-old man has appeared in court charged with the murder of Pc Keith Blakelock, who died during the Broadwater Farm riots in 1985.
Nicholas Jacobs is accused of killing the 40-year-old officer, who was stabbed as he tried to protect firefighters as they tackled a blaze at a supermarket during the height of the unrest in Tottenham, north London.
Wearing a grey tracksuit, bearded Jacobs spoke only to confirm his name and date of birth during a short hearing at Westminster Magistrates' Court.
He was remanded in custody to appear at the Old Bailey on Friday.
Prosecutors announced on Tuesday that Jacobs had been charged over Pc Blakelock's death.
He and his colleague Pc Richard Coombes were attacked on October 6 1985 during the disorder in north London, which was sparked by the death of Cynthia Jarrett who collapsed and died during a police raid on her home.
