A Boston man charged with robbing a Dunkin’ and two other businesses in the city was on federal supervised release at the time of the armed robberies, according to the U.S. Attorney’s Office.

Akeem Lahens, 33, has been charged with one count of affecting commerce by armed robbery, in connection to a string of commercial armed robberies in late April and early May. Lahens is currently in state custody on related charges, and will appear in Boston federal court at a later date.

The three armed robberies were of: Boost Mobile in Jamaica Plain on April 26; Cricket Wireless in Jamaica Plain on April 27; and Dunkin’ in Dorchester on May 4.

“Law enforcement believed that the robberies were connected and the perpetrator was likely the same person, as the suspect’s appearance in surveillance footage and witnesses descriptions was the same,” the U.S. Attorney’s Office said in a statement.

“Additionally, in each of the robberies, the suspect allegedly brandished two large knives, made a verbal demand for money, forcibly took money from the store and forced or attempted to force the victims into a rear room or bathroom of the store,” the feds added.

On May 5, Lahens was arrested on state charges related to the armed robberies.

Police during a search of Lahens’ residence in Dorchester found two knives and sandals allegedly worn by the robber in the April 26 robbery.

According to court records, Lahens at the time of the armed robberies was on federal supervised release after pleading guilty on April 26, 2021 in the Southern District of New York to five counts of robbery. Lahens was sentenced to 30 months in prison, followed by three years of supervised release.
