How to delete spam URL's

Hi Guys,

I just checked my google webmaster is showing these types of multiple url

https://websensepro.com/jailbroken/evasion-iphone-5-jailbreak-7-0-4/

But they dont exist in the backend I searched everything in database in wp-content folder and refresh my install completely but still unable to find the issue, question is why google is indexing these URL’s ?
