Police: Serial store robber strikes again in Inman Square; clerk gets into argument with him

Cambridge Police report the man who's been sticking up convenience stores in the Boston area over the past few months, struck again around 9 p.m. on Monday at a Cambridge Street convenience store.

According to police, the man, about 5'11" and 30-35, went up to the counter, lifted the bottom of his hoodie to show off his gun and demanded money from the register. Police say the clerk told him he couldn't open the register unless somebody made a purchase:

[The clerk] asked the suspect to show him the gun but the suspect stated just give me the money. [The clerk] opened the cash drawer and handed the suspect approximately $100.00. At 9:06 p.m. the suspect fled the store with the cash exiting the store heading right towards Hampshire Street.

Police say the man has robbed or tried to rob more than 20 stores this year.
