Orange County authorities say the a man seen on surveillance video is also connected to other robberies at two other Verizon stores.
During the most recent robbery in Santa Ana, security footage shows a man entering the store at night, carrying a black plastic rolling tote box and pulling out a gun that was tucked into his waistband.
The suspect orders the victims to get on the floor of the inventory room and loaded his bag with cellphones, tablets and money.
The robbery suspect is being described as a Hispanic man, 5'10 to 6 feet tall and weighing between 220-250 pounds.
The police say other robberies at Verizon stores on July 14th in Garden Grove and the Seal Beach theft on February 25th is most likely to have been committed by the same man.
The department has released the footage, asking anyone to come forward if they recognize the man or have other information related to the thefts.
