A teenager in eastern China was detained by police on Monday in connection with the stabbing death of his mother in a row over a dog. Police alleged Shao Fuming, 13, hacked 37-year-old Yang Yan to death with a cleaver on Saturday night at their home in Jianhu county, Jiangsu province, after they had an argument. Officers detained Fuming on Monday after Yang’s body was found, the police’s Weibo feed said. A neighbour said the death happened after Yang killed Fuming’s dog in an effort to discipline her son, Red Star News reported on Wednesday. “His mother thought he played with the pet all day long, so she threw it to its death in front of him,” the neighbour was quoted as saying. Fuming was detained by police at a 24-hour restaurant after spending more than a day there, the report said. He had ordered a cup of water and ate his own biscuits, restaurant staff were quoted as saying. Yang raised the boy on her own as her husband was a migrant worker who spent most of the year away from home, the report said.
