The police Bomb Squad was called this morning to remove a hand grenade from a South Philadelphia elementary school.
The grenade was a dummy, police said.
Students at the Taggart Elementary School at 4th and Porter Streets were temporarily evacuated to another school after the device was found on a desk in the building's first floor police office about 8 a.m.
They were allowed to return after the Bomb Squad squad removed the device about 8:45 a.m. and explosives sniffing bomb dogs swept the school as precaution.
Philadelphia Police investigators are trying to determine how the dummy grenade ended up in the school.
