RICHMOND, Va. (AP) — Virginia Tech says gunshots have been reported on campus, and authorities are seeking a suspect.

The campus-wide alert at 12:36 p.m. said: "Gun shots reported- Coliseum Parking lot. Stay Inside. Secure doors. Emergency personnel responding. Call 911 for help."

The suspect is described as white male wearing gray sweat pants, gray hat with neon green brim, maroon hoodie and backpack.

A message left with the university wasn't immediately returned. Campus police referred all questions to the university.

A student gunman killed 32 students and faculty and then shot himself on the campus in 2007.
