A man was executed Thursday for an arson attack on a bus that injured 30 in the eastern province of Zhejiang.

Bao Laixu, 35, set fire to a bus that had more than 80 passengers onboard on July 5, 2014, in the provincial capital Hangzhou. Of the injured, 20 sustained serious burns. The youngest was seven years old.

Bao himself also sustained extensive burns and had to have his feet amputated.

The city's intermediate people's court deprived him of his political rights for life in the first-instance verdict on Feb. 12 and then sentenced him to death.

During the trial, Bao pleaded guilty to arson. He said that his crime was an expression of revenge on society and that he wanted to end his own life because he had suffered from tuberculosis for years.
