Josh Duggar of TLC’s 19 Kids and Counting has confirmed to People that in 2006, as a teenager, he molested several underage girls—including some of his sisters. Duggar also announced that he will resign as executive director of the Family Research Council.

“Twelve years ago, as a young teenager, I acted inexcusably for which I am extremely sorry and deeply regret. I hurt others, including my family and close friends,” Duggar said in a statement to People.

“I confessed this to my parents who took several steps to help me address the situation. We spoke with the authorities where I confessed my wrongdoing, and my parents arranged for me and those affected by my actions to receive counseling. I understood that if I continued down this wrong road that I would end up ruining my life.”

A police report was filed in 2006, but, because the statute of limitations had passed by the time allegations were formally made, Duggar avoided prosecution.
