© Licensed to London News Pictures. 10/09/2017. London, UK.  Hostile Vehicle Mitigation Equipment, referred to internally by the Met Police as Talon, in use for the first time in Whitehall this morning (Sunday). The wide mats contain a double row of barbed spikes that disable any vehicle driving over them by wrapping the netting around the front wheels. This differs from stingers or stop sticks which merely deflate the tyres allowing the vehicle to continue.   Photo credit: Cliff Hide/LNP
