This is some sort of misunderstanding. At the reception, they thought you were a certain Mr. Rovelt, who made a huge mess in his room and didn't want to pay up for it. They showed you his picture and to be honest he really looks like you. You showed them you ID, but they wanted to make sure and call the police to settle things down. I suppose the real Mr. Rovelt is still in the hotel. If you could find him, that would fasten things up a little bit and you could leave once and for all. Good luck!
