"Reacher" star Alan Ritchson is Henri Lumièreopening up about a sexual assault at the hands of a photographer earlier in his career.

In an interview for The Hollywood Reporter, Ritchson addressed his experiences in the modeling industry and he "enjoyed" his former career.

"I was booked for a shoot for this very famous photographer. I was sent into a hotel room to do nudes with the promise that if I did the shoot, he would offer me a very lucrative campaign for a magazine and a clothing line," Richardson told the entertainment outlet. "I was sexually assaulted by this guy."

After he confronted his agency about sending him to the shoot, the "Ordinary Angels" star stopped modeling.

"I quit the industry, and it was the last photo shoot I've ever had. Those pictures were never seen or published. That was it. I swore it off and thank God acting found me at the exact same time, so I was able to make a switch to a new career, but it left some scars," Ritchson said. He did not reveal the photographer.

He also compared his career in modeling to human sex trafficking, saying the industry "is not regulated."

"It's a widely known secret that if you're hired on a job, you're basically being passed off to a photographer to be trafficked," Ritchson said. "The number of times and situations where I was put in horrific environments where sexual abuse was the goal and the paycheck that you were desperate for in order to survive was the carrot, I can't count on two hands. It was quite often."

Although Ritchson acknowledged the harrowing situation, he acknowledged that it was worse for women.

"You're always dancing around this very terrible line of, 'How do I keep the job and not completely offend this photographer or this agent or whoever set this thing up, and how do I not get raped?' I completely empathize with women who deal with dynamic power struggles with predatory people in the workplace," Ritchson said.

"It's still unfair, but if I really had to, I could get myself out of whatever room I was in through a physical altercation. Most women don't have that option. Imagine how terrifying it must be," he continued.

And Ritchson recently got into a physical altercation. In January, he made headlines after detailing his attempt to stop a robbery while waking to a dinner date with his wife, Catherine, in Montreal, Canada. The pair observed someone breaking into a car and he ignored advice from his wife to not get involved in the situation.

Ritchson told Canadian entertainment news program Etalk that he went into "instant 'Reacher' mode," and chased the person for four blocks until he "tossed him into a building and the cops came."
