A Sussex County grand jury returned an indictment Monday charging Earl Bradley with more than 55 new counts alleging sexual abuse of about two dozen additional children.
Bradley, who was arrested in December, pleaded not guilty last month to charges outlined in a 471-count indictment accusing him of sexually abusing 103 children.
All the crimes in that indictment were based on videotapes seized by investigators.
Monday's indictment was based on interviews with parents of other Bradley patients.
Bradley is being held in lieu of $4.7 million bail on charges including rape, sexual exploitation of a child, unlawful sexual contact and continuous sexual abuse of a child.
