Police arrested an unresponsive man found with a gun on the campus of a North Hollywood junior high school Monday morning.

The incident began at around 7:15 a.m. at Oakwood Secondary School, at 11600 W. Magnolia Boulevard. Police were called when someone saw a man with a gun on the school’s grounds, said Officer Norma Eisenman, an Los Angeles Police Department spokeswoman.

Arriving officers found a man lying on the ground. Eisenman said they “tried to make contact,” but the man did not appear to respond.

They took the man into custody, Eisenman said. He had not yet been identified.

It was unclear if any students were on campus at the time of the police response.
