Two Dunkinâ™ Donuts shops â” one in West Roxbury and another in Nashua, N.H. â” were robbed Tuesday night by a white male suspect wearing black clothing that covered most of his body.
The two stickups were the 13th and 14th robberies of Dunkinâ™ Donuts locations in Southern New England since March. Thirteen have occurred in Eastern Massachusetts; the Nashua robbery was the only one out of state, occurring about 15 minutes north of the Massachusetts state line.
The first robbery was reported at about 7:15 p.m. Tuesday at the shop at 119 East Hollis St. in Nashua. The suspect entered the store brandishing a black semi-automatic handgun, forced an employee to empty a register, and fled on foot with an undetermined amount of cash, apparently jumping into a car a short distance away, said Nashua Police Lieutenant Denis Linehan.
Linehan said he suspected the doughnut shop robber may have been involved in several other crimes in the Nashua area, including a street robbery in Hudson, N.H., also on Tuesday night.
Roughly an hour and a half after the first Dunkinâ™ robbery, at 8:45 p.m., Boston police received a report of another shop robbed at 1435 VFW Parkway in the West Roxbury section of Boston.
Witnesses told police that a male suspect walked into the shop brandishing a knife and forced employees to empty two cash registers. The suspect then took an undetermined amount of cash and fled on foot.
Police were hesitant to connect Tuesday nightâ™s robberies â” and have not made a definitive connection between any of the 14 robberies â”but Linehan said âœthere would be enough time to get from Roxbury to Nashuaâ in the hour-and-a-half between the two crimes.
In all 14 Dunkinâ™ robberies the suspect has been covered in black clothing and identified as a white or Hispanic male. A black handgun was used in all of the robberies except the West Roxbury one.
No injuries were reported in any of the robberies.
Dunkinâ™ Donuts and Canton police increased their reward from $2,500 to $10,000 on Friday for information leading to the arrest of a suspect, according to Canton police, who are coordinating the investigation.
The company, which is headquartered in Canton, did not return calls seeking comment.
