A man climbed the wall of a school building in China and sprayed a corrosive substance on kindergarten students inside, burning 51 kids and three teachers, according to the South China Morning Post.
The 23-year-old suspect cut wires and climbed over a wall into the Dongcheng Kindergarten in Kaiyuan, Yunnan province, where he sprayed sodium hydroxide on children and staff around 3:30 p.m. Monday.
The suspect was taken into custody about 40 minutes later, according to the report. Police believe he carried out the attack “as a revenge on society.” The students and teachers were taken to local hospitals where two of the injuries are considered serious, but non-life-threatening.
Exposure to sodium hydroxide can cause irritation to the eyes, skin, and mucous membrane, as well as an allergic reaction, according to the Centers for Disease Control and Prevention. Eye and skin burns, as well as temporary hair loss, can also occur.
