A South Boston man was arrested on charges that he robbed a convenience store and threatened an employee with a knife, police said.
Officers responded to the Cumberland Farms on East Fifth Street in South Boston about 11 p.m. Sunday after they received reports of an armed robbery, police said.
Peter Farrell, 22, was arrested Wednesday and is being charged with armed robbery, assault and battery with injuries, and shoplifting, police said.
When the officers arrived at the store, an employee told officers he had been robbed at knifepoint.
The victim said he was closing the store when the robber walked in, came around the counter, and threatened him with a knife. The suspect demanded the worker get on the ground and began taking money from a cash safe, police said.
After stealing from the safe, police said, Farrell tried to use the touch screen to open the cash register but was unable to. He then demanded the victim open the register, and the victim complied, police said.
