A Bent County sheriff's deputy has been arrested in an Internet child porn sting after allegedly sending a partially nude photo of himself to an investigator posing as an underage girl.

While visiting an Internet Web site using the screen name "heteague" this month, Deputy Hubert Teague was told he was communicating with a girl under age 15 and typed, "Wow young," in response, according to an arrest affidavit sworn by investigator Mike Harris of the Jefferson County district attorney's office.

Describing himself as a married, 34-year-old sheriff's deputy, Teague asked the investigator posing as a girl for a photo of herself.

After receiving an image of "a child in a swimming suit," Teague allegedly typed: "If I can say withing bein (sic) too bold . . . nice breasts. Can't help am just a horny old man on here tonight lol," he said, using the Web shorthand for "laughing out loud," according to the affidavit.

The sting was played out between Jan. 10 and Jan. 23, as Teague and Harris posing as the girl exchanged text messages. Teague also spoke on the phone with a woman investigator posing as the girl.

Teague is accused of e-mailing the supposed girl a graphic semi-nude photo of himself, the investigator wrote in the affidavit.

Teague is also accused of asking the supposed underage girl to provide nude photos of herself.

Teague appeared Monday in Jefferson County Court, where he was advised of his rights. His bail was set at $10,000.
