Betty Lou Lynn had her wallet stolen at a shopping center in Mount Airy, the birthplace of Andy Griffith.
The Mount Airy News reports that police arrested Shirley Walter Guynn of Cana, Va. He's being held in Surry County Jail on a $10,000 bond. It was not immediately clear Thursday whether he has a lawyer.
In an earlier interview with the newspaper, the 83-year-old Lynn said she moved to Mount Airy after being robbed three times in Los Angeles. In the TV series, Thelma Lou was the girlfriend of Deputy Barney Fife, played by Don Knotts.
