Three people were shot and injured at a cookout event at the Delaware State University campus Saturday evening. Police are looking for the shooter, according to reports.

The shooting happened at approximately 8 p.m., at a fraternity and sorority event that had been sanctioned by the university. The three injured people were taken to nearby Kent General Hospital, suffering from injuries that were described as not life-threatening by DSU spokesman Carlos Holmes, in an interview with the Associated Press.

A second shooting incident, in which there were no reported injuries, took place in the parking lot of a DSU-run student housing complex several hours later.

School officials sent out an alert to students, notifying them of the second incident, and released a description of a suspect, the News Journal reported.

Police armed with assault rifles, as well as a helicopter and patrol cars responded to the scene.

University officials advised students to remain indoors, in an emergency email sent to all students, WBOC-TV reported. Students who live on campus were told to return to their dorms and visitors were told to leave the grounds, according to a statement released by DSU President Harry L. Williams.

“The safety of our students continues to be paramount and our police will aggressively continue their investigation until an arrest or arrests are made in this shooting incident,” Williams said.

Delaware State University Police and Delaware State Police are actively investigating the incident. No possible motivation for the shooting, or the names of any possible suspects have yet been released, WPVI news reported.
