A police officer who was stabbed a number of times in a “frenzied” machete attack is seriously injured but will recover, police have said. The patrol officer was stabbed at about midnight on Thursday after attempting to stop a van in Leyton, east London. The vehicle’s driver, aged in his 50s, failed to stop and then got out of the van and attacked the officer with the machete. The policeman, aged in his 30s, managed to use his Taser despite having been stabbed, with the attacker then arrested by another officer. Detective Chief Superintendent Richard Tucker appeals to the public for any information concerning the attack.
