Cops collared a thug yesterday whose stray bullet wounded a 15-year-old girl in Queensbridge last weekend, police said.

Day Bryant, 37, of Harlem, allegedly fired his gun at 5:15 a.m. Sunday at the Queensbridge Houses.

A round went through the victim’s window and hit her in the hand, cops said.

Bryant was busted yesterday after a witness identified him. He was charged with reckless endangerment and weapon possession.
