This guy is a rapist?

Hi so this is kind of tricky. I threatened to go to the police over this guy who was forcing himself on girls... I posted something about him for his friends on my story.. not mentioning his name just for his friends. Should I actually go to the police about this? Or is he gonna try to sue me? And should I not go to the police?

Also I’m aware this can be considered libel, even if it was true... But I can counter sue him for harassing me on Twitter for two years for harassment.
