A Bangor High School student was placed under arrest Thursday morning after a search of the student's belongings uncovered marijuana, drug paraphernalia and a handgun.

According to a letter sent to parents by Principal Paul Butler, the student's belongings were searched under suspicion of marijuana use and possession.

The school resource officer was in the building at the time of the incident (about 10:45 a.m.) and arrested the student, who was removed from campus, according to the letter.

"Situations like this are extremely rare in our school," reads the letter. "Federal law and school policy are clear and firm in establishing that a student found to be in possession of a firearm on school property faces the expulsion proceedings."

"Students have been in classes with teachers observing a normal school day routine as the situation was handled swiftly through excellent communication and support of the school resource officer," the letter concludes.

Bangor police on Thursday said the firearm had been reported stolen a few days prior. Police did not disclose whether the gun was loaded.
