Massachusetts police say they have arrested an 18-year-old after he threatened to burn down the town and "take out" students at the local high school on social media.
Police say parents called Wednesday night to report the threats made on Instagram by former Marshfield High School student Andrew Lomuscio.
Officers quickly located him and he was involuntarily committed for a mental health evaluation at Beth Israel Hospital in Plymouth as they sought an arrest warrant. Eventually a warrant was obtained, and Lomuscio was arrested by Plymouth police.
Authorities say Lomuscio has since been arraigned on charges of threats to commit a crime, electronic threat to use a firearm to disrupt a school and threats to evacuate or disrupt a school.
Marshfield School Superintendent Jeffrey W. Granatino said in a statement, "Our primary concern is the safety and security of every student who is entrusted to our care. The district/school administration and police department take this responsibility very seriously and will continue to do so. Our guidance department and counseling staffs will be ready to assist any student who might be impacted in any way."
Lomuscio is being held without bail pending a dangerousness hearing. It's unclear if he has an attorney.
Marshfield police officers were also present on campus Thursday morning "for safety purposes," according to the school district.
The investigation is ongoing.
