The Los Angeles Police Department is assisting Cal State Northridge officials in a search for a possible gunman on campus.
Officer Fred Queto at the LAPD's Devonshire station said there have been no reports of shots fired or students injured, and that it was unclear whether the suspected gunman is still on campus.
According to an emergency notification on the school's Facebook page, police received a report at 10:27 a.m. of a man who indicated he had a gun. The man was described as 5-foot-8 with short spiky hair. He was said to be wearing a white T-shirt that says "human rights violation" and short jeans.
