After failing to get his hands on the cash, the man tries to flee only to find the door now locked.
At that point, the man starts hitting the door with his fists, but cannot break through. So, he picks up a coffee machine, smashes the glass door and flees the area.
The suspect is described as a black male, 20 to 25 years old with a medium build. He was wearing a dark grey hooded jacket with a gray hooded sweatshirt underneath, blue jeans, black sneakers and a dark mask covering the lower part of his face.
Police believe the suspect probably suffered some cuts to his hands and face when he broke the window to the store and jumped out to escape.
