The NYPD has released a sketch of the sneaky crook who smacked a woman in the head with a blunt object and robbed her in Little Neck last week — an incident that raised questions about whether it might be related to similar robberies that occurred elsewhere in Queens.

Law enforcement sources said the robbery occurred at about 7:30 a.m. on April 2 in front of a home on Marathon Parkway near Beechknoll Avenue.

According to authorities, the 60-year-old woman approached from behind by the suspect — described as a black man standing 6 feet tall — who exited from a nearby vehicle. According to a wanted poster on the 111th Precinct‘s Twitter account, the suspect frequents areas of the precinct and the 112th Precinct, which is based in Forest Hills and is dealing with a pattern of similar robberies.

Police said the perpetrator struck the woman in the head with an unidentified object, then forcibly removed her purse, which contained just $15 in cash.

The crook was observed re-entering the vehicle that fled the scene southbound on Marathon Parkway. The victim was treated at Long Island Jewish Medical Center for a head laceration.

Both the 111th Precinct and 112th Precinct Twitter accounts shared last week wanted posters of the suspects involved in the April 2 incident and the Forest Hills robbery pattern.
