BERLIN — German police were searching for a man who attacked and injured at least five people in the western city of Bielefeld early Sunday.

Police said four of the victims suffered serious injuries and were being treated in different hospitals after the suspect attacked revelers in front of a bar in the city center with a sharp object and then fled the scene. They said the four severely injured were all men between the ages of 22 and 27 from Bielefeld or nearby towns.

They also said they could not rule out the possibility that more people were injured in the attack.

German news agency dpa reported that the revelers were soccer fans from a local team who defended themselves against the attacker before he fled. The city’s Arminia Bielefeld soccer club won its match on Saturday, and with it became 3rd division champions.

According to police, the attacker — whom they identified only as a 35-year-old Syrian living in Germany — was probably also injured in the face.
