Nassau County police have released a video of a knife-wielding man they say is responsible for eight store robberies between March 1 and April 10.

The video shows the thief before and after he robbed a Dunkin’ Donuts in North New Hyde Park on March 1 at about 11:20 p.m., police said.

The suspect, who is described as about 6 feet tall, 170 pounds and between 25 and 30 years old, is seen entering the store wearing a dark sweatshirt and sunglasses. About 20 seconds later, he’s seen walking out of the shop with his hand covering his face.

In addition to the New Hyde Park robbery, police say the man in the video has robbed a 7 Eleven in Bethpage, a Subway sandwich shop in North Merrick and five other Dunkin’ Donuts — two in Plainview, one in East Meadow, one in Oceanside and one in Massapequa Park.

According to police, the suspect follows the same pattern in most of his robberies. He waits to enter the targeted business until no customers are inside. He then displays a large knife, demands cash and flees on foot, police said.

Early Monday morning, a spokeswoman said police were trying to determine if the suspect was also responsible for the robbery of a Williston Park Dunkin’ Donuts on April 8.

But they have since ruled out his involvement, noting that the suspects’ descriptions did not match, police said.
