Police are searching for the suspect who stabbed a man at a San Diego State University fraternity party just after midnight Sunday.
San Diego Police say a 20-year-old man was trying to break up a fight at the party in the 5000 block of College Place around 12:25 a.m.
As the fight escalated, an unknown suspect stabbed the man three times in the back.
The victim was taken to a local trauma center for non-life threatening injuries.
The suspect is still on the loose, police say, and SDSU police have taken over the investigation.
