Police are looking for a knife-wielding purse snatcher who followed a woman down an Astoria street before grabbing her bag.
The suspect approached the 36-year-old woman from behind near 38th Street at about 1:30 a.m. Sunday.
The chilling video shows him sneaking up on her with a knife in the air, and then shows their shadows as they struggle over the bag.
He fled in a black vehicle, police said.
Anyone with information is asked to call Crime Stoppers at 1-800-577-TIPS.
