Wilson High School students were briefly held inside classrooms before lunch Friday after the school received a bomb threat on the phone just before 10:30 a.m., officials said.
Long Beach police with bomb-sniffing dogs searched the campus but did not find any device or indication of a threat on the campus, police spokeswoman Jennifer De Prez said. The threat was deemed not credible.
“Our school remains safe,” Principal Kim Holland said in a statement to students and parents.
Students were kept inside for about 25 minutes and the school went back to normal operations at 11:25 a.m., according to the note.
The incident scared parents, some of whom went to the school when they got a notification text about the lockdown.
“It’s a scary thought, something like this close to home,” said Yuridia Jaimes, who was waiting for her ninth grade son. She said he texted her while she was running errands that there was “a school shooter or a bomb threat” and sent her pictures of the police on the campus, so she rushed down.
The lockdown comes a day after a shooting at a Santa Clarita high school that killed two students and wounded three others.
