-Astonishing footage has emerged of the moment a Good Samaritan shot and killed a man who was attacking a police officer in the middle of the road.

Ashad Russell has been called a hero after he gunned down armed suspect Edward Strother while he was beating Deputy Dean Barde on the ground in Estero, Florida.

The newly-released video of the November shooting shows Strother pinning Deputy Bardes to the road after the cop chased him several miles on I-75 before finally pulling him over.

Motorists stopped to watch the incident unfold, and some took their phones out and started filming.

But Russell decided to take the matter into his own hands, and took out his gun instead.

Officer Barde can be heard pleading: 'Shoot him! Shoot him!' as he struggles with Strother on the floor.

Russell, who has a concealed weapons permit, steps out of his car raises his gun, and fires three shots, all of which hit Strother.

Seconds later, Russell dropped his weapon and slowly walked away to wait for first responders to arrive.

On the film three shots clearly ring out as the witnesses describe seeing Strother on top of the cop...
