Red foxes have been known to frequent populated and urban areas, and they generally pose no danger to humans. If anything, it can be the other way around. It is important to take certain precautions to make sure smaller foxes do not get stuck in trash and the like. As Wildlife Aid says on their video, "All of this could have been avoided by simply rolling up the net or putting it away."
If you see a fox in any sort of distress, calling one of your local wildlife rescue services should always be the first course of action. The Humane Society of the United States has some tips on how to coexist peacefully with urban foxes.
