A man on a bus in Hangzhou set fire to himself, and the vehicle, injuring over 30 people on July 5.
It took about 20 minutes to extinguish the blaze by which time the bus was gutted, and 15 people were seriously injured, including the arsonist.
Passers-by tried to help the passengers, and put out the fire. The owner of a nearby newsstand handed out all his bottled water to pedestrians, so they could pour water onto the victims, 163.com reported.
An investigation revealed that the man started the fire with banana water, which is a highly flammable, colorless liquid that can cause explosions.
There have been a number of bus fires in recent years, including one in Xiamen when 48 people died, and over 30 were injured in 2013. A contributing factor is the poor security design of buses in China, according to Tencent News.
