MILFORD – Police say a Mont Vernon man was the driver of the getaway car in the armed robbery of four New Hampshire convenience stores, including a Cumberland Farms in Milford.

John Kalantzis, 38, of Manchester, was arrested about 45 minutes after a 6 p.m. robbery at a Manchester convenience store Monday.

Police say Kalantzis was found in the passenger seat of a car driven by Michael Crawford, 45, of Mont Vernon.

The gray 2011 Toyota Camry matched the description of the vehicle used in the robberies, according to Manchester police, and a witness in the parking lot of Mammoth Road Convenience in Manchester provided police with a description of the vehicle and license plate.

Police say Kalantzis was involved in all four armed robberies that began early Monday morning, around 1:24 a,m. when a man dressed in a black hooded sweatshirt showed a knife to the clerk at the Cumberland Farms store at 142 Nashua St., near the Milford Oval.

Kalantzis was charged with robbery and as a felon in possession of a dangerous weapon and was scheduled to appear in the 9th Circuit Court-Manchester on Tuesday, April 28. He was also placed on a 72-hour hold for probation/parole.

After the Milford robbery, similar robberies were reported earlier Monday in Auburn and in Goffstown.

Crawford has not been arrested, but charges against him might be forthcoming, police said.
