Multiple people were shot, including one student, after a shooting broke out at a residence hall at Oklahoma State University, police said.

The shooting erupted at around 3.40 a.m. Sunday at Carreker East residence hall, the OSU Police and Safety said.

The exact number of victims is unknown, but one was identified as an OSU student. All victims are being treated at hospitals in Oklahoma City and Tulsa, according to OSU Chief of Police Michael Beckner.

The circumstances leading up to the shooting are not immediately clear.

Initial reports indicate that the shooting occurred when some partygoers returned to the residence hall after “a large, private party” at an off-campus location disbanded, police said.

They are urging anyone who doesn’t live in the residence hall to avoid the area as law enforcement investigates the scene.

“There is no ongoing threat to campus,” authorities said.
