Police have arrested a 13-year-old boy in connection to the shooting of another 13-year-old boy inside the NYCHA Seth Low Houses in Brownsville.

Officers responded to 131 Belmont Ave. just before 2:45 p.m.

The boy was shot in both hands, his thigh and grazed by a bullet on his left knee, authorities say.

EMS took him to One Brooklyn Health-Brookdale University Hospital Medical Center where he is expected to recover.

The boy is facing charges for criminal possession of a weapon and reckless endangerment.

Police are still searching for another male dressed in all black, wearing ski masks, who ran from the building.
