Oh I found out how he did it, only Admins can do it.

First you remove the thread normally, then you view the removed thread (by using the recent changes page and clicking on the removed threads name). Lastly, on this page in the same area (on the lower right of the post) where you normally would remove a thread, it allows you instead to deleted it.

In other words its like removing a removed thread, kind of odd.
