Knicks mania turned into complete insanity in Times Square when fans smashed and tore apart several school buses in the packed party hub — including one that was left completely engulfed in fire. One bus was completely torched after the maniacs lit pieces of clothing on fire and tossed it inside — even as their fellow havoc-makers danced on the roof. Wild footage shows the maniacs ripping the buses to shreds as they stood parked near the 42nd Street subway station. The NYPD ultimately intervened around 2:30 a.m. — well over an hour after the hooligans started the school bus carnage. Police said early Sunday that no arrests had been made.
