The NYPD is looking for a man who allegedly approached a woman with a drawn knife and sexually assaulted her in a Bed-Stuy alleyway last month before lifting her cellphone and fleeing.

According to the police, the man ran past the victim, a 24-year-old woman, around 5:50 a.m. on Sunday, August 21st on Louis Place near the corner of Atlantic Avenue. He then allegedly turned towards her with a knife drawn and told her to follow him. Cops believe he led the woman to an alleyway between 19 and 19A Louis Place, and proceeded to sexually assault her. "He pulled down her pants and licked her genitals," cops said. "Afterward he turned her around and fondled her breasts and buttocks."

He then grabbed the woman's phone and fled the scene in an unknown direction.

Police released video of the suspect this week, who is described as 30 to 40 years old, with a mustache, about 5'6" tall and 190 pounds. He was last seen wearing a brown shirt and blue shorts.
