Once inside, he also used the piece of wood to smash taps, causing the room to flood.
Shortcliffe then went to another room and threw musical instruments and furniture around the room, damaging some beyond repair.
An extremely drunk Shortcliffe was found by police as he was leaving the second classroom and they arrested him. He was too drunk to be interviewed that night back at the police station.
Judge Bidois told Shortcliffe his actions had resulted in a significant expense and clean-up time for the school and being drunk was no excuse.
"This was just mindless, wanton damage," the judge said.
Under further questioning by Judge Bidois, Shortcliffe revealed that he had indeed been a student at the college in 1998. "It doesn't make sense. If you can do this amount damage to your old school, what else can you do to other parts of the community? To do this was just mindless stuff," the judge said.
