SIOUX FALLS, S.D. (AP) — An alert dispatcher is being credited with helping nab a man suspected of robbing a Sioux Falls taxi cab driver at gunpoint.

Police say a dispatcher at Yellow Cab Taxi late Saturday recognized the phone number of a potential fare as the same number used by a man who robbed a cab about 1:00 AM Thursday.

The dispatcher alerted police, who arrested the man near a restaurant. They say he had a BB gun that resembled a semi-automatic handgun.

The 20-year-old was arrested on charges of armed robbery and attempted armed robbery.

The driver who was robbed Thursday was not hurt in the incident.
