The dramatic moment police officers took down an armed drug gang after spotting one of their weapons on CCTV was caught on video.
Having seen the barrel glinting in the sun as it was handed between gang members in a Birmingham car park, the camera operator sent in their colleagues.
Body-cam footage of the confrontation captures an officer storming out of his police car and sprinting across the road.
He intercepts Makenzie Blackburn and yells: "Put your hands up, show me your hands.
"Get on the floor, get on the floor, get on the floor."
