, BEIJING, Sep 10 – Four people died and two others were injured in an attack at an old people\’s home in northeastern China on Friday which left the building on fire, a city official said.
The attack took place in the city of Yichun in Heilongjiang province, and the motive was not immediately clear, said a city district official who asked not to be named.
"The attacker ran away afterwards. The place was set on fire," she said, adding she was not sure if the blaze had been put out.
Police are investigating the incident, she said.
The incident was the latest in a series of recent killing sprees in China that some experts have linked to stress or mental illnesses as society becomes more fast-paced and socialist support systems wither.
Several people have attacked children and teachers at schools in particularly gruesome crimes that have shocked the nation.
At least six major attacks at schools have taken place since March, killing 21 people — including 18 children — and injuring more than 80.
In August, a Chinese court sentenced to death a man who murdered his girlfriend and four other people in a drunken fit of rage on New Year\’s Eve last year, state media reported.
