Bomb Threat Was 'Not Credible,' Says Winchester Police

Winchester Police continues its investigation into a threat made against Winchester High School on Monday morning, which forced officials to cancel classes.

Police said a school administrator received an email shortly after 5:15 a.m. The email included a ”non-specific bomb threat to the high school,” according to police.

School officials spoke to Winchester Police and they agreed to cancel classes and after-school activities on Monday as a precaution.

Winchester Police activated the Northeast Massachusetts Law Enforcement Council School Threat Assessment and Response System, which brought ”specially-trained law enforcement officials and school administrators from several other communities to assist Winchester,” said police.

In addition, K-9 units from the Bureau of Alcohol, Tobacco, Firearms and Explosives, Massachusetts State Police, NEMLEC and the Quincy Police responded to the high school.

Winchester Police said the threat was deemed “not credible” and local investigators are working with state and federal authorities “to determine the source of the threat.”

The bomb threat has been one of a series of threats made against schools in eastern Massachusetts over the past week, including Bedford, Swampscott and Westwood. Swampscott Police charged a 17-year-old in connection with the threat in that town.
