PHOENIX – Sierra Linda High School was placed on lockdown Monday morning after suspicious graffiti was found on campus, according to the Phoenix Police Department.

Around 6:45 a.m., graffiti mentioning a bomb threat, today's date and 10:30 a.m. was found on the side of a building on the campus near 67th Avenue and Lower Buckeye Road.

Due to the early hour, few students or staff members were on campus at the time, according to Sgt. Vince Lewis.

Officers searched the campus, but did not find any additional evidence. No suspects were located or identified.
