AUGUSTA — Cony High School was evacuated on Monday after police say a bomb threat was left in a bathroom for the second time in a week.

School officials reported finding a written threat in a bathroom around 1:50 p.m., said Sgt. Danny Boivin of the Augusta Police Department. Superintendent James Anastasio sent an alert to parents that indicated school officials “became aware of a suspicious message” around 1:40 p.m. and that students and staff were dismissed within 10 minutes.

In a news release, Lt. Kevin Lully of the city police said officers, detectives and bomb-sniffing dog teams are investigating the threat. He said students were told to go home and weren’t taken to another location.

It’s similar to an incident Tuesday, when the school was evacuated and closed for the day around 11 a.m. after school employees found suspicious writing on a bathroom wall that indicated potential danger. Afterward, bomb-sniffing dogs searched the building, which was declared safe by 3:30 p.m. that day.
