A gunman opened fire on a group of people in the Bronx — injuring four, a shocking new video shows.

The clip, shared online by the NYPD Tuesday, captures an unknown triggerman squeeze off several rounds near St. Ann’s Avenue and E. 147 Street around 8:10 p.m. on Aug. 3.

According to cops, a 22-year-old was man hit by gunfire in his left leg, a 30-year-old man was shot in the left arm, a 38-year-old man was shot in the left arm and a 25-year-old female was hit by a bullet in her left calf.

All were treated for the non-life-threatening injuries at area hospitals, cops said.

Police released the video in the hopes someone in the public could help identify the gunman.
