Responding to a report about two armed teens wearing camouflage clothing, deputies locked down the campus at 3195 Woodside Road at about 2:30 p.m. and evacuated about 100 people, including students and parents, deputies said.
After "swiftly" locating the two teenagers outside a fence at the school, deputies interviewed them and turned them and their weapons over to their parents, Deputy Rebecca Rosenblatt said.
The Sheriff's Office would not identify the suspects beyond saying that they are 16 and 17 years old and are from Redwood City and Woodside.
Asked whether the rifles were loaded, Ms. Rosenblatt said she did not have that information. Carrying weapons on any campus serving grades K-12 is a violation of Section 626.10 (a) of the state penal code.
The incident was handled as if it had been an "active shooter" situation, Ms. Rosenblatt said. "Obviously, the deputies took that (911) call very seriously," she said. Once the teens had been located, deputies downgraded the threat level, she said.
"There is a likelihood that they may get themselves a violation of the (penal code)," Ms. Rosenblatt said.
