I acted inexcusably: Josh Duggar on molestation allegation

Los Angeles: ‘19 Kids and Counting’ star Josh Duggar has apologised for "acting inexcusably" during his teenager years, hours after he was accused of molesting underage girls including his sisters, 12 years ago.

According to police report, Duggar, 14 at that time, sexually molested five young girls.

Parents Jim Bob and Michelle reported him to police but no charges were filed, said The Hollywood Reporter.

Duggar, now 27-year-old with three kids, responded to the allegations through a statement on Duggar Family's official Facebook page.

"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.

"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 counselling. I understood that if I continued down this wrong road that I would end up ruining my life," he wrote.

Duggar announced his resignation from Family Reserve Council, an organisation dedicated to preserving family values in America.

His wife, who is expecting their fourth child, also released a statement, admitting he confessed about his past before their engagement.
