Hiram Johnson High School in Sacramento was placed on a lockdown for more than an hour Wednesday afternoon after a threatening note was discovered in a trash can, police said.
Sacramento Police Department spokesman Officer Matthew McPhail said school officials decided to place the campus on lockdown “out of an abundance of caution.”
Gabe Ross, Sacramento Unified District spokesman, said the note was “an indirect threat where somebody threatened harm to him or herself.”
“It wasn’t an overt threat made to others in the school,” Ross said.
The lockdown was lifted at 2:17 p.m. after authorities determined it was a hoax, according to McPhail.
