Police are investigating another threat at San Ysidro High School, just weeks after a string of similar threat, a school representative said.
At about 1:10 p.m., the school got a message through Skype saying "the bomb will go off in the building in 1 hour," according to Principal Hector Espinoza. The message was not in the caller's voice he said.
San Diego Police were called to campus, and after conducting a sweep, they decided school should continue as usual with no lockdown. Espinoza says they made an announcement over the P.A. system, letting students and staff know about the situation. Parents were also contacted through the ConnectEd program.
A steady stream of parents have arrived throughout the afternoon to pick up their children. Police will remain on campus for the rest of the day.
