A St. Amant man who is a registered sex offender was arrested Wednesday on a count of indecent behavior with a 15-year-old girl, Ascension Parish sheriff’s Maj. Kevin Hanna said.

Troy Johnson, 38, was booked into Ascension Parish Prison on Wednesday. No bail had been set as of late Thursday afternoon, Hanna said in a news release.

The mother of a 15-year-old girl told deputies she had discovered that Johnson had touched her daughter inappropriately and had asked the girl more than once in recent months to have sex with him.

Johnson, who is in compliance with his annual registration with the Ascension Parish Sheriff’s Office, served time in prison after he was convicted of carnal knowledge of a juvenile, Hanna said.

He said Johnson is a Tier II sex offender, meaning he has committed a sex offense against a minor.
