Beijing, China (CNN) -- Police have detained a man accused of having killed at least three kindergarten students Tuesday in east China's Zibo City, Shandong Province, the city government said Wednesday, according to the state-run Xinhua News Agency.
Fang Jiantang, 26, was detained hours after the attack and has told police he was responsible, said the government in a statement.
In addition to the three fatalities, three other children and four teachers were wounded, it said.
Two of the teachers were in serious condition, it said.
Police found the two-foot (60-centimeter) knife that Fang said he used, the statement said.
