Police arrested Sebastian Calvo for suspicion of interference with staff, faculty or students of educational institutions. Calvo was a student at the college.

“I’m thinking someone just wanted to be a copycat or thought they could get a day off, but in the end we will have to do the work at some other point,” student Leon Fueller said. “We’re just going to cram in to a shorter schedule now. I just think it’s very stupid, it’s just burning money.”
