Waltham Man Arrested for Breaking Into Watertown High School and Using the Bathroom

An 18-year-old Waltham man allegedly snuck into Watertown High School on the evening of June 29, wandered around and used the bathroom before leaving the building, said Police Sgt. Thomas Grady.

The man was spotted, by a janitor, walking out of the principal’s office before leaving the building at about 8:14 p.m. The janitor called police and described the man as wearing a gray T-shirt and black shorts.

Police found a man matching the description walking on Catherine Street near Victory Field, Grady said.

“When questioned the man said he was curious and wanted to walk around the school,” Grady said. “He entered the rear door and used the bathroom and wandered around the building.”

Stephen E. McCoy, 18, of 140 Seminole Ave. in Waltham, was arrested on a charge of felony nighttime breaking and entering into a building, Grady said.

The rear door was likely left open because maintenance workers were coming in and out of the building, Grady said.
