Officials at Mt. Ararat High School in Topsham acknowledged Thursday that local police are investigating a threat of violence.

High School Principal Donna Brunette informed parents and students in a message posted on the school’s website that “a written message was found at the high school today indicating a potential act of violence would happen at the school in the near future.”

Brunette said there is no evidence to indicate that the threat was credible, but there will be heightened police presence around the school while the investigation continues.

She said there is no plan to close the high school on Monday. Students will not be in class on Friday because its a professional development day for school employees.

Any parent or student with information concerning the threat should contact the Sagadahoc County communications center at 443-9711.
