Dramatic POV footage shows armed cops smash a gang selling a gun in a deal arranged by a murderer from his prison cell.

Three men and a teenage boy, aged 17, from Birmingham were about to swap the handgun for two stolen cars with a criminal from London.

But cops got wind of the meeting and swooped on the gang as they waited in a Ford Fiesta in Selly Oak, Birmingham, on August 9 last year.

The raid, which was part of Operation Target, resulted in four men and one teen being jailed.

In the back of the Fiesta was a blank firing gun which had been converted into a live-firing weapon, and ten live rounds of ammunition.
