This is the moment police used a drone's thermal camera to swoop on a group of deer poachers under the cover of darkness. The suspected illegal hunters were arrested after being found hiding in their car in woodland near Beckingham ,Notts., on Friday (19/10). Using the thermal imaging technology Lincolnshire Police were able to spot the group in the pitch black woods and close in on their target. In the footage an officer can be seen circling around the trees with a police dog before several cops close find the crooks within minutes of deploying the drone.
