Robbers are running off with the dough, and Dunkin' Donuts and police in Massachusetts want to see this spree stop.

Massachusetts police met Wednesday morning at a venue provided by the Norwood Police Department to try to solve the case of the recent string of robberies targeting Dunkin' Donuts locations throughout eastern Massachusetts.

Police departments affected by the Dunkin' Donuts sting were invited to attend the meeting to help collaborate on motives and consistencies among the suspects and robberies, Norwood Police Lieutenant Peter Kelly Jr. told ABC News. Due to the ongoing nature of the investigation, Lt. Kelly could not reveal any details about the meeting or investigation at this time.

Tuesday night's robbery of a Dunkin' Donuts in Rockland, Mass., was just the latest of more than 20 Dunkin' Donut store robberies affecting 15 Massachusetts communities since March 2012. On Monday, two robberies occurred at Dunkin' Donuts shops in Bedford and Burlington.

A Newton Dunkin Donuts, pictured Oct. 3, 2013, was robbed at gunpoint with employees forced to floor; making it the 14th store hit in a recent spree.

And the Dunkin' Donut suspect or suspects are still on the lam.

Lt. Nick Zeoli of Rockland Police said that based on surveillance footage from the latest robbery the party was by himself, but it's not known for sure.

However, police continue to find links between the various crime scenes. "Based on the method by which the person used to come into the store, the weapon used, the description of the individual, it appears it may be related to the other robberies that occurred," Lt. Zeoli said.

According to the Burlington Police Department release, on Monday evening, a male suspect, described as "wearing a ski mask, black hooded jacket, jeans, black sneakers and black gloves," robbed a Dunkin Donuts located at 28 Winn Street. He brandished what appeared to be a black pistol and demanded money from the register, the release states.

The release continues, "The Burlington Police Department is working closely with area departments to identify the suspect. The Burlington Police have currently increased directed patrols of these type establishments and are encouraging citizens to notify police if they observe any suspicious activity."

In the meantime, Dunkin' Donuts said in a statement, "We are working closely with our franchisees and the local law enforcement in regards to the situation. Dunkin' Brands is offering a $10,000 reward for information leading to the arrest of a suspect, and we encourage anyone with information to contact the local authorities."

Lt. Kelly said that although detectives collaborated this morning, each police department is conducting its own investigation. "Anybody with a tip should contact the town where the robbery took place and leave them with whatever information they have."

A Dunkin' Donuts robbery occurred in a Norwood store on Aug. 8, 2013.

In light of the recent string of robberies, Lt. Kelly advises people to be aware of their surroundings and to be the best eyewitness they can when a crime is committed. "We don't need any heroes, we need help from the public in apprehending the person or people," he said.
