Kenneth Lee Hall was arrested Wednesday and jailed for violating the terms of his sex-offender therapy, a condition of his probation. Hall, 41, was convicted in May 1999 of sexual assault.
A merchant became suspicious when he read a flyer Hall dropped off at his business, offering to provide overnight baby-sitting for children ages 2 to 4, said Detective Bryan Fischer. The flyer said Hall would like to be a "big brother" for a handicapped girl between the ages of 2 and 4, and offered a place to stay for a homeless girl up to the age of 8.
The business manager found Hall's photograph and criminal history on a sex offender Web site and called 911.
Fischer said Hall placed a classified advertisement in a weekly newspaper in late March, offering to baby-sit young children.
Police are investigating whether anyone responded to the offers.
