You'll need to hold a demotion thread or blog for at least a week and have everyone vote on it. If the bureaucrat deletes it, you can contact Staff about it at Special:Contact/general, which you should do immediately anyway after you create it so that they can keep an eye on it. Do not make an actual poll. Every user needs to state yes or no to have the bureaucrat demoted. At the end of the week, you contact Staff about it again with the link above and give them the final result, with a link to it as well. Check User blog:Mira Laime/How to Deal With a Bad Bureaucrat for more details.

I hope that helps!
