A Texarkana man has been arrested for allegedly trying to extort Cole Vosbury, a contestant on the TV show "The Voice."

Caddo Sheriff Steve Prator says Harold Glen Martin talked with Vosbury several months ago about performing at a benefit concert. The deal was never finalized, and Vosbury left the area to compete on "The Voice" in California.

Once the program featuring Vosbury began airing on national TV, Martin threatened to defame Vosbury in the national media unless he agreed to perform several free concerts at Martin's discretion.

Caddo Sheriff's Detective Bobby Herring investigated the case and says there's no proof that Martin ever intended to produce a benefit concert. He also says Martin's threats have intensified as Vosbury's popularity has grown.

Martin was arrested at his home in Texarkana. He is expected to be transferred to Caddo Parish today. According to family members, neither they nor Vosbury will be making any statements at this time.
