A dramatic scene is unfolding in Center City, Philadelphia after a building collapsed at around 10:45 this morning, trapping several people.

Philadelphia police have ruled out any foul play and believe that 8-10 people were trapped in the collapse. Authorities believe that the demolition of an old pornography theater next door caused the dramatic collapse.

As you can see from this before and after photo from Buzzfeed, the building completely collapsed. UPDATE: The photo is a little misleading as the building was already under demolition. Here's a more recent photograph.
