More than 50 children in southwest China were injured in a chemical attack in a kindergarten, state media reported on Tuesday
According to CNA, the suspect climbed a wall to enter kindergarten and sprayed caustic soda.
An hour later, a 23-year-old man was arrested. The police said he wanted "revenge on society," Xinhua said.
The Washington Post reported that the Kaiyuan police found the man behind the school and cited his "problematic family background."
Sodium hydroxide, also known as caustic soda or caustic, attacks metals and tissues and can irritate the skin, eyes and mucous membranes, according to the US National Library of Medicine.
Similar attacks on schoolchildren have been carried out in China in recent years. Eight children were killed on the first day of school in Hubei Province in September, the South China Morning Post reported.
In January, a man with a hammer injured 20 children at a school in Beijing. In October 2018, 14 children were injured in a kindergarten in Chongqing during a knife attack. In a knife attack in Mizhi County in April 2018, several children died in a middle school.
