BLOOMINGTON, Ind. — Two Indiana University students were charged Sunday morning in connection with a stabbing that injured another student at a campus apartment building, school officials said.

University police arrested 18-year-old Zesen Shen and 21-year-old Kaiyu Lao, university 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 the victim, a 20-year-old 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 the victim and wounded him with a knife,’’ Land said.

University police Lieutenant Craig Munroe told the Indianapolis Star the student was stabbed in the back. The 20-year-old was taken to IU Health hospital in Bloomington with an injury that is not 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.

Police said that while a lock-down was not ordered, all on campus were urged to heed the call to stay inside as a safety measure.
