An 18-year-old Brunswick High School student is under arrest after reportedly making online threats against the school. 

Tyler Hrouda was arrested Monday at a local business along Pearl Road, after Brunswick Police were made aware of the threat. They contacted the school, who with the help of a resource officer and staff, were able to identify Hrouda. 

Hrouda has been charged with making a false report, and in a Facebook post from the Brunswick Police Department, detectives reportedly did recover a firearm during their investigation. 

The nature of the threat was not made public.
