University police arrested 18-year-old Zesen Shen and 21-year-old Kaiyu Lao, IU spokesman Mark Land said in a news release. Shen has been charged with intimidation and battery and Lao was charged with intimidation, Land said.
Police said Shen, Lao and a 20-year-old IU student were in the Tulip Tree apartment's parking lot around 3:30 a.m., Land said. Witnesses told campus police the three were there "to resolve a dispute when the suspects began chasing victim and wounded him with a knife," Land said.
University police Lt. Craig Munroe told the Indianapolis Star (http://indy.st/1ckrtoX) the student was stabbed in the back. The 20-year-old was taken to IU Health hospital in Bloomington with an injury that isn't life-threatening, Land said.
The incident prompted university officials earlier Sunday to tell students to seek shelter behind locked doors. The school gave students the all clear around 7 a.m. CDT.
