The robbery happened around 1:00 a.m. Tuesday in the area of 4717 Cedar Avenue in Southwest Philadelphia.
Police say the suspects approached the man and one pulled a gun on the victim, took his cell phone, and walked him to the Sunoco gas station at 45th and Baltimore where they tried to make him withdraw money from an ATM.
