GREENWICH — Central Middle School Principal Thomas Healy spent the last 24 hours reassuring parents that the school and its students were safe after a student made a “concerning statement” among a group of other students Thursday.

Healy first responded Thursday evening to the numerous inquiries he received about a potential threat to the safety of Central and its students.

“Administrators were informed that a student made a concerning statement among a group of other students and we handled the incident immediately,” he said in an email to the Central Middle School community.

After a thorough investigation, in conjunction with the district’s school resource police officers, it was determined that the threat was not credible, he said.

“Please know that our students and staff are safe and there is no credible threat of violence to the school community,” Healy said. “We take any threat seriously and investigate thoroughly.”

The Greenwich Public Schools declined to provide any details on the incident or the “concerning statement.”

As rumors swirled, he followed up with a second email to parents on Friday afternoon. Healy told parents that he had met with faculty before school started Friday morning to ensure staff members could support their students. The school-based crisis response team also met to ensure the emotional needs of staff and students are met “going forward.”

As a result of the meetings, staff and administration decided to convene a schoolwide assembly at the end of the first period Friday morning.

“We brought everyone into the auditorium where I spoke about the incident and I shared with them my understanding of their concern,” Healy said.

“I assured them that the school is safe and that I am taking every step necessary to accomplish my primary responsibility, which is to ensure the safety and security of every person at Central,” he said.
