The men are targeting Dunkin Donuts and hotels.
Police were able to release the image of one of the men believed to be involved in the robberies.
Investigators say the robbers strike in groups as large as five, and they have held up at least eight businesses in southeast Queens dating back to three days before Christmas.
The most recent incident happened at a Dunkin Donuts on the Grand Central Parkway around 3 a.m. on January 8. Twenty minutes before that, they hit a bodega on Union Turnpike.
In each case, at least one of the robbers was armed with a gun.
Three different hotels have also been targeted, on Jamaica Avenue and the Van Wyck.
So far, no one has been injured in any of the robberies.
The suspects usually wear ski masks and black clothing.
Anyone with information is asked to call police.
