Police are asking for help identifying the man they say robbed CVS on Chelmsford Street Thursday night aroun 8:30 p.m.

Police said they responded to the armed robbery and learned that a lone white male suspect had entered the store and proceeded to the pharmacy. The man passed a note and demanded that the pharmacy employee hand over some prescription drugs, police said.
