Police say the suspect was arrested about six hours after the robbery.
BROCKTON — A combined effort by detectives and patrol officers led to the arrest of an armed robbery suspect early Wednesday morning, about six hours after the incident.
Officers responded to Dunkin’ Donuts, at 321 Crescent St., for a report of a robbery about 8:06 p.m.
“One of the employees told police that a white male in his late 30s or 40s handed her a note,” said police spokesman Darren Duarte. “The clerk said the suspect had his left hand on the inside of his shirt as if he had a weapon.”
The man, who didn’t show a weapon, left the Dunkin’ with an undisclosed amount of cash, according to police.
Patrol officers and detectives began investigating the robbery by searching the area for the suspect and reviewing nearby surveillance video. Police say they learned the suspect, identified as Robert A. Ryan, fled in a white pickup truck through area surveillance video.
“Officers began their search for the suspect and a white Chevy pickup truck he drove away in,” Duarte said.
Shortly after 11 p.m., patrol officers spotted the suspect’s white Chevrolet Silverado pickup truck parked outside of 103 Main St. in the downtown. Detectives began conducting surveillance of the truck and say they witnessed two men enter it shortly before 2 a.m.
“Gang Unit detectives saw two men get in the pickup truck,” Duarte said. “When investigators approached the vehicle, they found one of the men who fit the description of the man who robbed the Dunkin’ Donuts six hours earlier.”
Ryan, 44, of 59 Ann St., Raynham, was arrested and charged with armed robbery.
Police say they did not recover a gun. The pickup truck was towed back to the police station as part of the ongoing investigation.
“Detectives confiscated a notepad from the truck which investigators believe the suspect tore paper from to write the note used in the robbery,” Duarte said.
The truck was photographed by a sheriff’s deputy with the Plymouth County Bureau of Criminal Investigation.
Ryan is scheduled to be arraigned Wednesday in Brockton District Court.
