Jerome C. Higgins of East Brunswick was allegedly smoking inside the school and tossed an unfinished portion of the cigarette into a trash can.

"The contents of the trash can, located in the custodian's office, caught fire and the blaze spread through the building," the Middlesex County Prosecutor's Office stated in a press release.

The 48-year-old was charged Monday with a disorderly persons offense; smoking is prohibited on school grounds.

The six-alarm fire began at approximately 7:45 p.m. Saturday and gutted the 50-year-old building within hours.

Students are slated to resume classes Wednesday at Middlesex County College.
