Students at Watertown High School were ordered to shelter in place for four hours Friday and were dismissed early after a bullet was found in a classroom, police said.
Lieutenant Michael Lawn said that a teacher found the bullet on top of a projector about 8 a.m. and that school authorities called police and notified parents with an automatic phone message. Police confiscated the bullet as evidence, Lawn said.
Police searched the building while students stayed in their classrooms . Police also used an X-ray machine to search student’s backpacks. But nothing more had been found, Lawn said.
There were no injuries reported, and everyone is safe, Lawn said. Full story for BostonGlobe.com subscribers.
