Police arrested Adam Wainwright shortly after they say he went into the store on Wadsworth and pretended to shop for some items before pulling out a handgun and demanding money from the clerk.
According to police, after he got some cash, he forced the clerk into a back room and ran off.
Authorities caught up with Wainwright about a half hour later when an investigator spotted him in different clothing nearby. When police approached Wainwright, they found evidence tying him to the robbery.
Wainwright is being held in Jefferson County Jail on charges of Aggravated Robbery and Second Degree Kidnapping.
He also has a warrant for his arrest for a theft case out of California.
