DETROIT, Mich. -- A U.S Justice Department official has been arrested on suspicion of traveling to Detroit over the weekend to have sex with a 5-year-old girl, WDIV-TV in Detroit reported.

John David R. Atchison, 53, an assistant U.S. attorney from the northern district of Florida, was arraigned in U.S. District Court in Detroit on Monday afternoon.

Prosecutors said Atchison flew from Pensacola, Fla., to Detroit on Sunday intending to have sex with a 5-year-old girl.

He was arrested at Detroit Metropolitan Airport.

He is charged with enticement of a minor to engage in sexual activity.

According to authorities, Atchison made contact with a detective working undercover for the Macomb County Sheriff's Department.

The detective, acting as the child's mother, allegedly arranged a sexual encounter between Atchison and the 5-year-old girl, police said.

In a deposition, detectives said Atchison suggested the mother tell her daughter that "you found her a sweet boyfriend who will bring her presents."

The undercover detective expressed concern about physical injury to the 5-year-old girl as a result of the sexual activity. Detectives said Atchison responded, "I am always gentle and loving; not to worry, no damage ever, no rough stuff ever. I only like it soft and nice."

The undercover detective asked how Atchison can be certain of no injury.

He responded, "Just gotta go slow and very easy. I've done it plenty," according to detectives.

The Macomb County Sheriff's Department and the FBI were a part of the investigation.
