Police responded to a shooting at Lincoln University in Pennsylvania on Saturday night.

(CNN) — At least one person was killed and six others were injured in a shooting at Pennsylvania’s Lincoln University Saturday night, during the historically Black university’s homecoming weekend, according to officials.

The shooting is the latest in a disturbing trend of violence surrounding games and homecoming celebrations across the country this football season.

A total of seven people were hit with gunfire after shots rang out near the school’s International Cultural Center, where homecoming crowds were celebrating after that afternoon’s football game, authorities said at a news conference early Sunday.

“That festivity was interrupted and decimated by gunfire. It was a chaotic scene, and people fled in every direction,” Chester County District Attorney Christopher de Barrena-Sarobe said.

Officials did not give details on the conditions of the six injured. Multiple gunshot victims were taken to hospitals in nearby Delaware, authorities told CNN earlier.

Several others were treated at the scene after being knocked to the ground and trampled as people ran for cover, de Barrena-Sarobe said.

Officials have not yet determined a motive in the shooting, but de Barrena-Sarobe said it does not appear to be a case “where someone came in with the design to inflict mass damage on a college campus.”

One person who was carrying a gun has been detained, the district attorney said, noting investigators are still piecing together information.

“We don’t have a lot of answers about exactly what happened,” he said, noting it is possible there were multiple shooters.
