Wrong plugin. Please remove.

I’ve requested a new subversion repository for my new plugin called Instagram Gallery Widget. Unfortunally i’ve uploaded into /trunk a readme.txt file referring to another plugin called “Special Recent Posts”.
For a while i had two plugins with the same name inside the WP repository. Now i’d like to completely remove my instagra-gallery-widget from the repository and search results.

Is there any method to do this? Thank You
