The Terrebonne Sheriff's department has arrested a 41-year-old man on allegations that he raped a three-year-old child he was baby-sitting. Sheriff Jerry Larpenter says a patrolman responded to a complaint of an incident that occurred on Friday, May 23. Larpenter said the mother of the youngster said her child complained of having been hurt by the sitter. Cobey Roberts of Houma was named as a suspect and he was eventually contacted and agreed to come to the sheriff's office. Larpenter said Roberts admitted to baby-sitting and inappropriately touching the child. Roberts was arrested today for aggravated rape and his bond was set at $1 million. If convicted, he faces possible life in prison.
