MADISON, Wis. -

A 32-year-old man has been arrested after Madison police said he robbed a man after taking him to a north side convenience store.

The incident happened just before 4 p.m. Saturday at the PDQ on Northport Drive.

According to police, James Pope offered a ride to a 19-year-old Madison man Saturday afternoon. Police said when they got to the parking lot of the PDQ, Pope demanded gas money from the victim before pulling out a knife and holding it to the victim's neck.

Police said the victim gave Pope money, then ran away on Northport. Later that evening, police said an officer stopped a car matching the description of Pope's. When the officer made the stop, he saw the driver matched Pope's description, according to police.

Police said Pope had a warrant, and a follow-up investigation developed enough information to charge Pope with the armed robbery, along with other charges.
