Possible shooting reported at Los Angeles County high school: Police

After reports that a person with a gun was seen on campus at a Southern California high school on Friday, police have detained one suspect, the Los Angeles County Sheriff's Department said.

Police had not yet confirmed whether the reports were true or whether any shots had been fired, a spokesman, Deputy Charles Moore, said.

Deputies were still searching Highland High School in Palmdale, California, around 8:15 a.m. local time (1515 GMT), a little more than an hour after the reports first arrived, the department said.

The spokesman said police received multiple reports of an armed man at the school, which is about 90 minutes north of Los Angeles. 

Sheriff's deputies also headed to a second school, Manzanita Elementary School, a few miles away after receiving reports that people thought they heard gunfire, according to another spokesman, Bob Boese.

"People heard shots, but there's no confirmation on that," Boese said.

CNN reported that three schools nearby were on lockdown. School district officials could not immediately be reached on Friday morning.
