Police Arrest Delaware Man, 51, for Gunpoint Robbery of Radio Shack in Riverside

Greenwich police say they've arrested a 51-year-old Delaware man in connection with Sunday's of Radio Shack in Riverside.

Police used eye-witness accounts to obtain a warrant Tuesday for the arrest of Ronald Brockenbaugh, of 152 Freedom Trail, New Castle, DE. He's charged with first-degree robbery, using a firearm while committing a felony, criminal possession of a pistol or revolver and fifth-degree larceny.

At about 3:15 p.m. Sunday, a masked man made off with a “small amount of cash from the day’s proceeds”after brandishing a handgun to order store employees into a back room at the Riverside Commons shopping plaza shop. No one was injured.

"Based [on] information obtained from witnesses, detectives were able to quickly identify a suspect," Lt. Kraig Gray, the Greenwich police public information officer, said in a press release. "The vehicle used during the commission of the crime was linked to this suspect and photo identification was also obtained from a witness."

Brockenbaugh is known to frequent Greenwich, Gray said.

Greenwich police worked with Delaware's New Castle County Police Department early on Tuesday to confirm that Brockenbaugh's vehicle was at home. Police had said Monday that the robbery suspect left the scene in a Green Audi A6 with a Delaware license plate. The county police in Delaware obtained a warrant to search Brockenbaugh's vehicle and inside it found the handgun believed to have been used in the Greenwich robbery, Gray said.

Brockenbaugh was taken into custody by the New Castle County police at 2 p.m. Tuesday, Gray said.

"The suspect is currently in the custody of the New Castle County P.D. pending adjudication of the local charges prior to his expected exradition to Connecticut," Gray said. "The Greenwich Police Department would also like to recognize the New Castle City (Delaware) Police Department for their assistance in this investigation."

Greenwich police on Monday had opened a tip line to bolster the investigation. The suspect had been described as a "black male of average height and weight." It is not clear whether the tip line was useful in this case. Police had said Monday that they would not release "photograph or surveillance [photos]," declining to say whether they possessed such images.

Sunday’s incident is the latest in a string of armed robberies targeting Greenwich shops. Greenwich police have made arrests in all incidents.

Two months ago at Riverside Commons, a man was arrested after a 24-hour CVS located eight doors away from the Radio Shack. The plaza is located directly across East Putnam Avenue from Exit 5 on and off ramps for Interstate 95, northbound and southbound. One month ago, two men who know each other were arrested following of chain stores on Greenwich Avenue — a CVS and a Subway restaurant — though each appears to have acted on his own.
