Robert Darling, 30, of Strickland Street in London, was arrested last week in connection with the raid at the Mount Pleasant Road branch of Thomas Cook in Royal Tunbridge Wells in July.
He now faces a charge of robbery and possession of an imitation firearm for the role police believe he played in the incident, KentOnline reports.
Earlier this year on July 9, police were called to the Cook store following the robbery during which a man brandished a fake black handgun and made off with a quantity of currency.
