It happened at 9:18 p.m. on December 23, at the El Gallo Grocery Store, located at 118 East Tioga Street.
Surveillance cameras captured the men enter the store, pointing handguns at an employee and forcing a customer on the floor.
During the course of the robbery, one suspect told the other to "shoot him (the employee) in the leg" as he took money from behind the counter, police said.
The suspects made off with an undetermined amount of cash from the store, plus $20 and a cell phone from two customers.
The first suspect is described as a Hispanic male, 5'7, stocky build, 210 lbs, wearing a ski mask, black Nike hooded jacket, black pants, and black boots.
The second suspect is described as a male with a light complexion, thin build, 185 lbs, wearing a black scarf around his face, black windbreaker, black pants, and black sneakers.
If you see these suspects do not approach, contact 911 immediately.
