Lockdowns at nearby schools lifted after bomb threat

SAN FRANCISCO -- Students at a San Francisco high school have been evacuated and downlocks at an elementary school and middle school have been lifted after a bomb threat earlier Friday morning.

Students at George Washington High School were sent home around 12:30 p.m. after school officials received a call from a person around 10:45 a.m. who said they were near the school and had a bomb, according to San Francisco Unified School District Officials.

Nearby Lafayette Elementary School and Presidio Middle School were briefly placed on lockout. The lockouts at the two schools have since been lifted, school district officials said.

Police responded to the scene and sealed a perimeter around the high school. Police and school district officials have not said whether they found anything to substantiate the threat.
