Police say the student has a shallow stab wound to his abdomen and is expected to be OK. He is recovering in the hospital.
Investigators say the stabbing did not happen on campus, but in front of a Mini Mart store on Pacheco Street in downtown Concord. They say he then drove himself to campus for help. They got the call at 7:56 this morning.
Officers have not been able to interview the victim.
"It's very early in the investigation to say what motivated this or what really happened. We know about his wound and approximately where it happened. We will have more details later today and be able to do an updated press release," said Lt. Mike Kindorf of the Concord Police Dept.
