After hearing gunshots, an off-duty NYPD officer tried to chase down a group of men involved in the East Harlem shooting—leading to another barrage of bullets that left one man injured. When the cop started trailing a group of men reportedly involved in a shooting near Lexington Avenue and 103rd Street last night at around 10 p.m., there was a second exchange of gunfire and a man was hit in the leg, the Daily News reports. It's unclear if the off-duty officer fired any shots.

"It does not appear that the off-duty [officer] shot the individual," a law enforcement source told the tabloid. Police scanner reports indicate that three men were taken into custody after the incident, and a police aviation unit was dispatched "in regard to airmail (objects being thrown down at the officers)" from a building at the corner of East 99th Street and Second Avenue. That's where the man wounded in the shooting was found by FDNY paramedics, who treated him for a non-life-threatening injury and brought him to Metropolitan Hospital.
