A bomb blast that killed eight people and injured dozens outside a kindergarten in eastern China was the work of a 22-year-old introvert who was among the dead, authorities said Friday.

The public security ministry said in a statement that the suspect was a man with health problems who rented a room near the school in Fengxian, where Thursday’s blast occurred.

Police found material to make a homemade explosive device at the apartment, which had the words “die”, “death” and “destroy” written on the wall.

The statement said the man, surnamed Xu, suffered from dysfunction of the autonomic nervous system, a disorder that can cause heart and blood pressure problems.
