DENVER -- A Fort Carson soldier has been arrested after officials said he tried to arrange sex with an undercover sheriff's deputy posing as an underage girl.

Sgt. Brian Kelly Wells, 28, of Colorado Springs, faces charges of Internet luring of a child, internet sexual exploitation of a child and attempted sexual assault on a child.

He arranged to have sex with an underage girl who was actually an undercover Adams County Sheriff's Office investigator during an operation targeting Internet predators, said Adams County sheriff spokeswoman Sgt. Candi Baker.

"Wells drove from Colorado Springs to a residence in Adams County where he had arranged to meet with the girl for sex," Baker said. "Wells arrived at the residence and knocked on the door where detectives met him and took him into custody without incident."

He was wearing his military uniform at the time of the arrest.

Baker said he was booked into the Adams County Detention Facility and will be released to the Military Police on Mar. 11.
