Three people were shot in Brooklyn early Wednesday morning, including a teen girl and boy, cops said.

The gunman shot a 15-year-old girl in the torso, and a 17-year-old boy in the rear.  The teen girl was taken to Brookdale Hospital in stable condition, and the boy is at Kings County Hospital.  The shooting took place at the Louis Armstrong Houses on Lexington Avenue, near Tompkins Avenue, around 4:30 a.m.

A 21-year-old man was shot in the back, and another female teen, 17, suffered a graze wound to her hand.  They are at Kings County Hospital and Woodhull Hospital, respectively, in stable condition.

Police are not sure what caused the bullets to start flying.

The gunman remains on the loose. No arrests have been made yet.
