Suffolk County Police have arrested a Lindenhurst teenager after he made a threat of mass harm online on Wednesday afternoon.
A 911 caller reported a 15-year-old male student at Brennan High School, located at 550 Mount Ave., threatened during an online chat involving other students from the school, to shoot people at the school.
The threat was not made during school hours.
Following an investigation by Second Precinct Crime Section officers and Second Squad detectives, as well as First Precinct patrol officers, the 15-year-old, whose name is not being released due his age, was charged with Making a Threat of Mass Harm, a misdemeanor.
He was released into the custody of family and will be arraigned at Suffolk County Family Court on a later date.
A defendant is presumed innocent until and unless proven guilty.
