The attacker was subsequently shot and taken to hospital, said a police spokeswoman. She added that there were no immediate signs that the assailant had a terrorist motive.
He had allegedly stolen a vehicle and caused an accident, after which he assaulted two policewomen who had been called to the scene, wounding one in the face and the other in the chin.
