The Metropolitan Police force said that two officers were trying to pull over a van in east London when a man leapt out and stabbed one police officer several times. Detective Chief Superintendent Richard Tucker said it was a “frenzied and unprovoked” attack. The officer, who is in his 30s, suffered wounds to his head and hands but managed to use a Taser to subdue the attacker. A man in his 50s is in custody. Tucker said the police officer is “seriously injured, but he will make a recovery.” Police say they don’t think the attack in the early hours of Thursday is related to terrorism.
