Authorities say Darrell Haynes was involved with a robbery of Heights Financial on December 17th.

Officers spotted Haynes sitting inside a car in Mt. Vernon on Wednesday when he was arrested. Denzal Haynes and Steven Collier were both already charged in connection with the robbery. Those two men had preliminary hearings yesterday, as they are also charged with two other robberies.
