Police arrested a 16-year-old boy who they suspect brought a gun on the Menlo-Atherton High School campus on June 6 during the Atherton school’s graduation ceremony.

At around 5:27 p.m. on Thursday, Atherton police officers who were working a security detail for the graduation were alerted by the high school’s security guard that a physical fight had broken out in the campus’ G-Wing, said Atherton Police Cmdr. Joe Wade. The graduation ceremony, which began at 4 p.m., was underway during the incident. Police said the incident did not interfere with the ceremony.

When police arrived at the scene of the fight, several suspects fled, according to Wade. One suspect tossed a gray item -- a shirt wrapped around a black and green .40-caliber Polymer 80 Glock style handgun -- into the bushes at the southeast corner of Ringwood Avenue and Arlington Way, he said.

Police caught up with the suspect, along with another boy believed to be involved in the fight, and detained them.

The suspect who officers believed tossed the gun, a 16-year-old from Redwood City, was arrested. He was booked into San Mateo County Juvenile Hall on counts of possession of a firearm in a school zone; being a minor in possession of a concealed firearm, ammunition, and a large capacity magazine; resisting arrest; and a probation violation, Wade said.

The case will be sent to the San Mateo County Juvenile District Attorney's Office for review, he said.

Officers also found a 15-round magazine carrying three .40-caliber rounds of ammunition during the incident.

The other suspect, a 15-year-old boy and Sunnyvale resident, was taken to the Atherton police station, and ultimately released to his parent, Wade said. Neither suspect attends M-A, he said.
