The robbery happened at 12:00 p.m. Saturday at the Mobile Zone communications store located at 114 West Girard Avenue.
In surveillance video taken from inside the store, the two suspects can be seen entering the business and approaching the counter.
According to police, the suspects asked the employee behind the counter about a cell phone accessory. Almost immediately, one of the suspects went behind the counter, pointed a handgun at the employee, and demanded money.
Both suspects then took money from the cash register drawer as well as an iPhone before fleeing the scene on foot.
It is also believed they fled onto the elevated train platform where they discarded their jackets and the iPhone that was taken during the robbery.
