Students and teachers at Watertown High School have been ordered to shelter in place this afternoon and will be dismissed early after a round of ammunition was found in a bathroom at the school, according to a automated message to parents from Superintendent Jean Fitzgerald.
The message said that school authorities would be dismissing the students as quickly but orderly as possible “out of an abundance of caution.”
An employee who answered the phone at the high school said everyone was safe.
The school is set to be dismissed by 1 p.m., said the employee, who did not give her name.
The incident comes two weeks after the high school was evacuated and dismissed because of a bomb threat. Police and bomb squads searched the building after the threat came in Dec. 5 and found nothing.
