San Francisco police evacuated Jose Ortega Elementary School in the City's Lake Merced neighborhood after someone found a note about a bomb threat.
After a three-hour search turned up nothing, police allowed students and teachers back inside the school shortly before 11 a.m.
Police said the call came in at 8 a.m. Friday morning regarding a possible threat to the school at 400 Sargent St. The school district sent out an email saying "a note with a bomb threat was found."
Students would be allowed to return to class when there is an "all-clear," police said. Police on the scene said the threat did not seem credible.
