The New York City Police Department is looking for a man wanted for a series of violent robberies of women in Queens.

Investigators say he's attacked five women in Astoria since July 28.

In at least two cases he threatened the victims with a knife.

Police also say he's punched and choked other victims, and was wearing a surgical mask during the most recent robbery on Sunday.

In total, the man is believed to have gotten away with nearly $200 cash and multiple credit cards. 

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-8477, or text CRIMES and then enter TIP577, or visit
