Police need help finding a man wanted for a series of robberies at stores in Manhattan and Brooklyn since February.

They allege the man has hit nearly 20 delis and bodegas and one cell phone store between Feb. 16 and this past Tuesday.

Officers say the man walks into the businesses with a gun and steals cash and cartons of cigarettes.

They say he struck three times last month including June 24 (when surveillance video was shot) and four times this month.

Last Tuesday, police say he used another man as a lookout.

No injuries were reported in any of the incidents.

The suspect is described as 20 to 30 years old and between 5 feet 6 inches and 5 feet 8 inches in height.

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