(AP) — A convicted sex offender has been arrested in Omaha, accused of sexually assaulting a 5-year-old girl.

Douglas County Jail records say 41-year-old Charles Hardymartin was arrested Saturday night and remained in custody Monday. He faces sex assault and other charges, including one alleging a sex registry violation. Online court records don’t list the name of his attorney.

Nebraska Sex Offender Registry records say Hardymartin had been sentenced in June 2009 to four to five years in prison for sexually assaulting a child. He was released from prison on Jan. 7, 2011.
