A US student, who was filmed yelling "let's rape some bitch", has been accused of sexually assaulting a woman previously.

In the video, filmed in June, a man can be heard chanting "rape" and shouting obscenities including "let's rape some sluts".

The Orlando Sentinel reported that the man was identified by the alleged victim of a sexual assault in October last year as her attacker.

The footage led to the suspension of the University of Central Florida's Sigma Nu fraternity, to which the student belonged.
