Both of the crimes were caught on camera, and authorities fear that the group will only get more dangerous the longer they are on the lam.
Officials believe the same men are responsible for committing two armed robberies less than 15 minutes apart, beginning just after 5 a.m. Tuesday.
The video shows three masked men who are clearly carrying guns rushing into the Irish Minimart on McLean Avenue.
One man pointed his gun at a woman standing at the counter before ordering her to lie on the floor, while the other men jumped behind the counter and went through the register while a male employee stood there with his hands in the air, complying with the suspects' demands.
About 15 minutes later, police believe the three same masked men barged into a Dunkin Donuts on Park Avenue and followed the same MO. The men jumped behind the counter and grabbed every dime and dollar they could find.
Police say the men are quick, desperate and no doubt very dangerous.
They also believe this is second time the same men robbed Dunkin Donuts location.
Fortunately, no serious injuries have been reported.
Anyone with information is asked to call police.
