PISCATAWAY, N.J. (AP) — A former student at Rutgers University returned to its business school and stabbed a faculty member, another student and then himself on Friday, officials said.

The university sent out an alert just before 3 p.m. saying there had been a stabbing at the business school and telling people to avoid the area and take shelter. About a half-hour later, it sent another alert saying a suspect was in custody and the area was safe.

Ultan Cullen said he was walking into the business school when the first police officer arrived on the scene.

“He was flooring it through and just like going straight to the other side of the road and just runs right out of the car and into the building,” Cullen said. “Just cop car after cop car started showing up.”

Cullen said he soon saw an ambulance pull up and paramedics carry a man out on a stretcher.

“There was a lot of blood,” Cullen said. “He had one of his arms propped up in the air. It was really messy.”
