KA_Yarmouth_Mattacheese Middle School_11915YARMOUTH – Yarmouth Police and Dennis-Yarmouth Regional School officials investigated a possible threat made on the Mattacheese Middle School Monday.

After an initial investigation, it was determined no threat existed and students were allowed to remain in school.

The following is a statement issues by the school principal.


Earlier today we were made aware of a message that could have been a possible threat. At that time we instituted our safety protocols and consulted with public safety representatives. It was determined by all parties that there was no credible threat. Students returned to their regular school day just after 11:30.

Please be aware that the safety and security of our students is our top priority.
Thank you for your continued support.
