(NewsNation) — Queen Camilla is opening up about a painful chapter of her life.

Camilla shared on BBC Radio 4’s “Today” show that when she was a teenager, she was attacked by a man she didn’t know.

“When I was a teenager, I was attacked on a train. I’d sort of forgotten about it. But I remember at the time being so angry,” she told BBC racing commentator John Hunt on the special edition of the show. “Somebody I didn’t know.  I was reading my book, and this boy – man – attacked me, and I did fight back.”

Camilla remembered her mother asking her, when she got off the train, why her hair was messy and why a button was missing from her coat.

“I had been attacked, but I remember anger, and I was so furious about it, and it sort of lurked for many years,” Camilla said.

Queen Camilla is a longtime supporter of assault victims

Camilla has a history of supporting victims of rape, sexual abuse and domestic violence through her public work, according to People magazine.

Her announcement comes at a time when her brother-in-law, former Prince Andrew, has been heavily scrutinized over his relationship with convicted sex offender Jeffrey Epstein.

The connection and controversy led to King Charles III stripping Andrew of all his royal titles and honors.
