Surveillance footage of a brutal robbery helped cops nab three teens after they robbed an elderly woman in Peter Cooper Village, police said yesterday.
The 74-year-old victim was walking near her building on Peter Cooper Road shortly before midnight Sunday when the trio grabbed her purse, cops said.
The plucky woman held on and was dragged a short distance before the thugs finally wrestling the purse free.
They fled with cash, credit cards and a cellphone, police said.
Investigators used video surveillance footage from a nearby camera to identify the suspects, all 16, sources said.
They were busted on Monday and, when confronted with the incriminating video, allegedly confessed.
All were charged with gang assault and robbery.
