A 19-year-old Pennsylvania College of Technology student from Wellsboro faces charges related to allegedly setting off a firework inside a dorm room Tuesday, which led to smoke conditions and the evacuation of students in the building and a search that revealed further explosive material allegedly possessed by the student.

Christopher C. Greenawalt was arraigned before District Judge Kirsten A. Gardner on charges of arson and related offenses.

The smoke was discovered at 11:29 a.m. Tuesday at Lancaster Hall, 250 Rose St., according to Penn College Police.

A small explosive device was detonated from a dismantled firework, police said.

A search warrant was obtained and found additional materials, including a plastic bag which had the writing on it – “highly explosive.”

Authorities also found a duffle bag with four separate bags of suspected explosive material, a large emptied out firework that was wrapped in electrical tape and fuses.

Assisting Penn College Police and state police in this investigation were members of the FBI.

District Attorney Tom Marino authorized charges of aggravated arson, arson, causing or risking a catastrophe, criminal mischief, reckless endangerment, and disorderly conduct.
