They have confirmed that the arsonist died in the burning bus:
Police in Xiamen have identified a suspect they believe responsible for the bus blaze that killed 47 people on Friday.
On Saturday, authorities named Chen Shuizong, a native of the city in Fujian province, as the prime suspect. He was among the passengers who died.
According to the city government's information office, police raided Chen's home and discovered a will "in which he revealed despair about his life".
He was identified through footage recorded by a security camera on the bus, a police officer close to the investigation said on condition of anonymity.
He said initial findings suggested at least 10 liters of gasoline was used to start the blaze.
Flames swept through the rapid transit bus as it traveled on an elevated road between the city's Caitang and Jinshan stations at about 6:20 pm.
The vehicle had been carrying about 90 passengers, Huang Wenhui, spokesman for the city government, said on Saturday.
He confirmed the death toll and said 34 people had also been injured.
