Easter pranksters

CARLSBAD, Calif.- Forget being glued to their seats: Kids at a suburban San Diego high school couldn't even get through their classroom doors Friday.

With only a day to go before spring break, vandals plugged locks on all the exterior gates and doors on campus with super-strength adhesive.

"A teacher who always gets there early called me on my cell phone and said, 'Guess what?'" said Carlsbad High School principal Margaret Stanchi. "But I didn't guess this."

Roughly 100 doors were sealed shut sometime before the first staff arrived at about 6:30 a.m., Stanchi said.

Custodial staff quickly unsealed the lock on a building with 27 classrooms, but the rest of the school's 3,000 students were sent to sit in gym bleachers until their classrooms were opened, one by one.

Surveillance video taken at the school failed to provide any clues to the prankster's identity, Stanchi said.

Carlsbad police were investigating the incident.
