A high school in Bakersfield, Calif., was evacuated Friday after officials said a pipe bomb had been found in a bathroom, NBC affiliate KGET-TV reported.
But after a bomb squad was dispatched to North High School, it quickly became apparent that the "bomb" was really a plumbing tool that had been left there by a worker.
Students were earlier evacuated to the football stadium, and then released to their parents or taken home by school bus.
