This is the moment a man allegedly used a sledgehammer to break into a train depot, before smashing up walls, windows, toilets and computers.
The man appears to climb into a Network Rail compound near Victoria station before going on the rampage.
After allegedly taking a pair of keys to a Network rail van, footage shows him driving it through metal gates, damaging the vehicle.
This was an utterly meaningless rampage. By stealing a van and driving it so erratically, this could have had lethal consequences for either the man himself or a passing member of the public.
