A 31-year-old Palm Coast man is facing five counts of sexual battery on a child younger than 12 and three counts of lewd and lascivious acts on a child younger than 12.

Thomas Underwood was arrested Thursday afternoon at his home.

Flagler County detectives said Underwood began molesting his victims more than 16 years ago. They said some of the victims, who were 8 and 10 years old at the time, are now coming forward to report being victimized by a younger Underwood.

One victim, who was 8 at the time, said that Underwood, who was then 15, sexually molested her while he was babysitting her, according to detectives.

Underwood is being held in the Flagler County Inmate Facility without bail.
