Parkour man falls from Cockermouth school roof
A young man has been seriously injured falling through a window while doing parkour, or free running, in Cumbria.
He fell from the roof of a school in Cockermouth.
Parkour involves running or jumping freely over or around obstacles, using just the body, often in an urban environment.
Cumbria police have warned the activity is "exceptionally dangerous" with "fatal or life-threatening" consequences and can be illegal.
A spokeswoman said: "Though this may appear to be an exciting activity, it is inherently dangerous to do it at height on the roofs of the buildings."
The force said it was aware of reports of young people climbing on various unsafe roofs in the town and asked parents to warn their children of the dangers.
