Re: What can i do...?

Your friend is the victim of sexual harassment and abuse by legal definition.  There is little that you, personally, can do to help him - he must take the steps to help himself before this episode becomes a focal point for the rest of his life.  ndvh.org is the site for the National Domestic Violence Hotline - there are lists of resources state by state.  He can also contact his local law enforcement, but I would suggest to him that it would be far more effective to align himself with an advocacy organization, first.  Unfortunately, sexual harassment of men is so under-reported because of the stigma and ridicule that they experience, as victims, by law enforcement and the legal system.  He needs to be prepared for this through counseling.
