A lockdown at Granite Bay High School has been lifted and classes have resumed, according to the Placer County Sheriff's Office.
Sheriff's spokeswoman Dena Erwin said the lockdown was initiated about 10:30 a.m. after a suspicious note was found in a restroom. A sheriff's school resource officer was on site at the time, and additional law enforcement officers were summoned .
Erwin said officers and school officials chose to err on the side of caution, directing students and staff to shelter in place during the investigation. A search of the campus turned up nothing out of the ordinary, she said.
The lockdown was lifted at noon.
