Put that URL in your robot.txt file to let Google know that you dont want this URL to index. and Google will not index it more. Then in Google webmaster create new url removal request and put that URL there. Google will remove it from index.
You can block all search engines from indexing your site via robots file. Or use the google webmaster tools to remove any site from google search engine.
There is an option in Google webmaster tool to send a request to remove the indexed page!!!! it will take time....
If you are permanently deleted your pages from your server than u can submit your request using Google webmaster tool. Follow these steps login to your webmaster tool account(If you don't have than make a account than verify your site uploading meta tag of Google or a new page) --> than click on your site url which on url you want to delete --> Go to tool option --> click on Remove URLs option --> and submit your request to removal. Hope it will help you
As already mentioned you can get them to skip your page by using your robots.txt file, to speed up the removal of the page from the index once you have altered you robots.txt file go into Google webmaster tools and ask them to remove the page in there.
