OAKLAND PARK, Fla. -

Georges Richardson The Broward Sheriff's Office made four arrests in connection with a robbery at a T-Mobile store in Oakland Park.

Police arrested 21-year-old Georges Richardson (pictured, right), two 17-year-old boys, and one 16-year-old boy. The four were each charged with armed robbery with a firearm.

About 9:45 a.m. Monday, two of the four -- wearing masks and hoodies -- stormed into the store at 881 E. Commercial Boulevard and forced employees into the storeroom, where they took 36 new cell phones worth about $21,000, investigators said. The other two acted as look-outs from a nearby Dunkin' Donuts. They then left in two cars.

Police later found one of the cars, and inside it were the masks and hoodies used during the robbery, police said. The car led police to the suspects, and investigators recovered a gun and the cell phones.

Richardson was also charged with two counts of violation of probation.
