The police say that this man is a suspect in five robberies.

The authorities are looking for a man suspected of committing five robberies — including three in the East Village — over the course of four days.

The first incident occurred on May 12 at 315 East 18th Street, when the thief approached a 26-year-old woman at around 10:30 p.m., brandished a knife and demanded her wallet. He fled the scene empty-handed.

The next morning the suspect struck again, this time in our neighborhood at Second Avenue and East Houston Street. The police said he grabbed a 27-year-old woman from behind, covered her mouth and once again failed to steal his victim’s wallet.

Investigators said that on May 14, the suspect struck twice more in the East Village. At 1:20 a.m. he wrapped his arm around a woman’s neck at 202 East Sixth Street and stole her cell phone. Then, the police said that at 9:10 a.m. the man covered another woman’s mouth at Lafayette and Bleecker Streets and demanded her wallet. He again left empty-handed.

In the fifth incident, the police said that the man pushed a 24-year-old woman against a wall at 44 Wall Street at 3 a.m. and stole her cell phone.

Police said the man — who is pictured above in a pair images from surveillance cameras — is roughly 6 feet tall and weighs about 200 pounds.
