A 17-year-old boy was shot amid the chaos in Times Square early Sunday after the Knicks' historic NBA championship win, police said.

The teen was shot in the foot at about 2 a.m. at 42nd St. and Broadway, police said. Medics took him to Bellevue Hospital.

Police took three persons of interest into custody, with charges against them pending.

The shooting comes as out-of-control fans lit a school bus connected to the World Cup on fire nearby, set off fireworks and damaged vehicles.

Cops have not yet released a total tally of arrests made during the mayhem.
