Seven people were shot on Lincoln University of Pennsylvania’s campus during Homecoming weekend, the Chester County District Attorney said.

The district attorney’s office confirmed that seven people were shot Saturday night. Officials said local, state and federal law enforcement agencies are investigating the shooting.

The shooting happened just after 9 p.m. during the school’s tailgate and yardfest event near the football field. The school is located on Baltimore Pike in western Chester County, about 50 miles from Philadelphia.

The DA’s office is asking people to avoid the area as surrounding roads have been blocked off.

CBS News Philadelphia spoke to a witness who said he saw one person receiving CPR.

People were seen running for cover, and several others are being treated after being knocked to the ground and trampled, officials said.

The condition of the victims are unknown at this time. It is unclear what led to the shooting.

In an Instagram post, the university said counseling services will be available on Sunday starting at 10 a.m. for students and staff who need support.

Pennsylvania Gov. Josh Shapiro said on X, “I’ve been briefed on the shooting at Lincoln University tonight, and my Administration has offered our full support to President Allen and local law enforcement. Please avoid the area, continue to follow the guidance of local law enforcement, and join Lori and me in praying for the Lincoln University community.”

“Please join me in praying for the students and faculty of Lincoln University, as well as the brave members of law enforcement on the scene. It appears there has been a mass shooting there tonight, ” said Chester County Commissioner Eric Roe in a post on Facebook.

Founded in 1854, Lincoln University is the nation’s oldest degree-granting historically Black college or university.

The DA’s office encourages anyone with any information about this shooting to call 1-800-CALLFBI.
