John Leroy Moore, 34, of the 5600 block of Nelson Street in Philadelphia, was arrested on Tuesday. He is currently being held behind bars on $50,000 cash bail.
Police say Moore was one of four men who robbed Hymie's back on the night of July 14th.
Investigators say the suspects went into Hymie's, at 342 Montgomery Avenue, and ordered everyone in the restaurant to get on the ground in the front of the store.
The customers were then told to turn over their cell phones and wallets. One of the suspects ordered the manager to open a register and turn over the cash.
The suspects then fled through the back door.
Moore's arrest comes a few weeks after another suspect, Michael Schaefer, was arrested in his Olney home.
The search continues for two other suspects.
