Laila Rouass was raped by someone she knew.
The 47-year-old actress reported the assault to police but was advised not to take her allegation further as it was unlikely to result in a conviction to her attacker.
Taking to Twitter after Bill Crosby was jailed for three to 10 years for drugging and sexually assaulting a woman, Laila posted: "It's encouraging to see Cosby jailed for his crimes.
"I was raped by someone I knew and once I found the courage to report it to the police I was advised by them not to take it any further because it would be unlikely to get a conviction. I shed so many tears."
The "Safe" actress - who is engaged to snooker legend Ronnie O'Sullivan - previously revealed she was still experiencing the effects of being caught up in last year's terrorist attack in Barcelona, which killed 13 people.
She said: "There is this thing called catastrophic thinking.
"I get on a plane and I think it's going to crash.
"It's sort of easing, I've not had any help or anything but it's getting better."
Laila previously revealed how she and her daughter Inez, 11, escaped the attack in August 2017 by hiding in a restaurant freezer.
She said: "There was pandemonium, there were gunshots, people running into the restaurant, I didn't know what was going on.
"I was right in the middle of it, I thought there was a gunman like what happened in Paris, so we ran downstairs to the basement.
"As I was going down, the chef was coming out of the door, so I pushed my daughter through there and it's where the cold room is so I put her in there, covered her up with boxes.
"It's weird, I wasn't really thinking about myself, I just thought "How do I get her safe?"
"I shut her in and I thought "What if I get shot and they can't find my daughter?" so I thought, "I will get her a coat so she's warm and I will get a pen and I will write a note and put it in my pocket, in case I get shot, to say my daughter is in the freezer."
"She was crying, but funnily enough after she's been absolutely fine.
"It's just when we go to a restaurant she does look for the exits, she says "Can we sit next to the exit?" "
