Xuzhou Police on Tuesday announced the capture of a man thought

He is accused of having sold 250 grams of thallium nitrate to
Chang, a student at the China University of Mining and Technology

of CUMT Publicity Department told China.org.cn.
"The three poisoned students are still hospitalized and
recovering well. Doctors at Beijing Chaoyang Hospital have allowed

hometowns for further treatment," a CUMT official told China.org.cn
