Police have arrested a suspect in the latest robbery of a Subway store in Berks County.

The holdup happened around 8:15 p.m. Monday when a masked man armed with a gun walked into the Subway on Howard Boulevard in Mount Penn.

The suspect, identified by police as Andrew Folk, turned the cash register around and started grabbing money himself, investigators said.

Folk, a former employee of the store, was arrested five hours after the robbery, police said.

Police are still looking for one other person in connection with the holdup. Anyone with information that can help with their investigation is asked to call Crime Alert Berks County at 877-373-9913.

The same Subway store was robbed in April, and a suspect was subsequently arrested.
