BEIJING (AP) — Police were hunting Friday for a man in northeast China suspected of killing 10 people, including his wife, father and son.

The official Xinhua News Agency said 10 bodies were found at a bathhouse and car wash in Anshan city in Liaoning province.

Xinhua quoted police as saying they were searching for Zhou Yuxin, the 33-year-old owner of the bathhouse and car wash.

It said Zhou’s wife, son and father were found dead, along with a female bathhouse worker, three family members of Zhou’s landlord and three car wash workers.

Xinhua quoted the police as saying extramarital affairs were possibly behind the killing spree, which happened late Wednesday night and early Thursday morning.

Telephone calls to police, government and Communist Party media offices in Anshan rang unanswered Friday.
