The Westport Police Department was notified Wednesday of the unspecified threat, which was made in late August.
The individual threatened violence at a school near his home on Sept. 8, police said.
The Federal Bureau of Investigation traced the threat back to a Westport public school student. The student’s parents were notified and were cooperative with investigators, police said.
The student was interviewed by the FBI and Westport investigators. At no time did the youth have access to any weapons, police said.
The student was charged with second-degree breach of peace and second-degree threatening. The juvenile student was not identified by police, and the nature of the threat was not explained.
"The Westport Police Department has been working closely with Westport Public School administrators and we are confident the safety of students is not in jeopardy," police said in a statement.
"Additionally, the school administration will be addressing the issue and following up with appropriate disciplinary action," police said.
