A Delaware State University spokesman said Monday one person was shot at an off-campus residence hall. The school’s campus in Dover, Delaware, was locked down and the shooter remains at large.

The Delaware State University shooting occurred after 4 p.m. EST at the school’s Living and Learning Commons, school spokesman Carlos Holmes told the Associated Press. The main campus was placed on lockdown about 90 minutes later. Police have not made any arrests.

The shooting victim suffered a non-life-threatening injury and was taken to Kent General Hospital, NBC Philadelphia reports. It’s unclear if the victim is a student at Delaware State.

In 2007, two Delaware State students were shot on campus, the AP reported. A third freshman, Loyer Braden of East Orange, New Jersey, was charged in the incident. One of the shooting’s victims, Shalita Middleton, later died from her wounds.
