The initial post almost makes it sound like he was outside of his room and naked, chasing the housekeeper down the hallway of the
hotel... which does present a somewhat amusing mental picture, not least because in a presumably more public space one has the sense that the alleged victim had a better shot at avoiding assault.
However according to the rest of that story and the rest of the news reports, this incident happened in his private suite, which was made up of several rooms and the "hallway" was part of that private space.
The current story is that the hotel employee entered the suite to do routine housekeeping, thinking that the guest was not present. Mr. Strauss-Kahn, however, was in the bathroom, from which he emerged, still naked. He then locked the door of the suite. Allegedly he assaulted the woman twice after the brief chase which is apparently the source of so much amusement - once in a bedroom, and again after dragging her into the bathroom.
So, uh, yeah. HILARIOUS.
