We had a wild bear with cubs go into the dumpster for food at our university campus, this is North America of course.

I don't know London at all but I would hazard that you have foxes and other wild animals living in the city, just well hidden. We have coyotes that have taken up residence in many American cities.

Foxes are everywhere in London, including the City, and are a common sight.
