Ten San Diego-area high schools were targeted by threats of violence Thursday morning, prompting lockdowns and police sweeps that turned up no immediate hazards, authorities reported.
Authorities said there was no immediate indication of who might be responsible for the threats.

The first local campus to receive a menacing call was San Ysidro High, which was phoned about 9:15 a.m. by someone who made a vaguely ominous claim that "something was going to happen" there soon, said Manny Rubio, spokesman for Sweetwater Union High School District. Officers searched the classrooms and grounds, then gave an all-clear about 11 a.m., he said.
Starting at about 9:30 a.m., meanwhile, threats about shootings or explosives were received at 10 San Diego Unified School District campuses: Clairemont, Crawford, Kearny, La Jolla, Mira Mesa, Morse, Patrick Henry, Point Loma, San Diego and Scripps Ranch high schools, SDUSD spokeswoman Ursula Kroemer said.
Administrators put the campuses on lockdown while San Diego police conducted sweeps.
As a precaution, all HS's NOT in lockdown do have a police presence on campus.

The security measures remained in effect in the late morning, by which time officers had found nothing that posed any kind of danger to students or staff, Kroemer said.
At 12:35 p.m., the lockdowns at Patrick Henry, Morse, San Diego, Scripps Ranch, Crawford, Mira Mesa and Clairemont high schools were all lifted, and district officials said those schools would release students at their normally scheduled.
The lockdowns at Kearny, Point Loma and La Jolla high schools were lifted 30 minutes later.
