Chinese police have arrested a man suspected of starting a bus fire that killed 17 people, state media has reported.
Flames engulfed the vehicle outside a furniture store in the northern region of Ningxia. A further 32 people were injured in the attack.
A spokesperson for the Ningxia fire department said firefighters took 10 minutes to extinguish the blaze.
Police surrounded and seized the suspected arsonist after launching a manhunt, the People’s Daily reported on its microblog.
Detectives in Helan county were investigating the blaze. State media did not speculate on a motive for the attack.
Traffic accidents are relatively common in China where safety standards are often lax. There have been several bus fires in recent years.
Last year, a 35-year-old man was executed for starting a fire on a bus in the city of Hangzhou in July 2014 that injured 33. A court said Bao Laixu had been seeking revenge against society and had wanted to kill himself after a relapse of tuberculosis.
In 2013 a suicidal man started a fire on a bus in eastern China that killed 47 people including himself, state media said.
