Westerly — Police arrested a Westerly man who they say stole a large amount of prescription drugs from the CVS pharmacy on Granite Street.

Police said at about 2:57 this morning Officer Jed Giguere was on patrol on Granite Street when he saw a man running through the CVS parking lot towards John Street.

The man was wearing a knit hat, sunglasses and appeared to have clothing covering his face. The man refused to obey Giguere's commands to stop. Giguere saw a large plastic bag drop from under his sweatshirt.

After a brief chase, Giguere apprehended the suspect. While placing the man under arrest, a female employee ran out of the CVS and reported that the store had just been robbed. The bag was found to contain a large amount of prescription narcotics.

Patrick S. Marr, 25, was charged with robbery, crimes against pharmacies and resisting arrest.

CVS employees said that Marr walked into store, went to the pharmacy counter and demanded that employees fill a plastic bag with narcotics. No weapons were shown and there were no injuries.
