This is the moment a police officer in Arizona who has now been kicked out of the force shoots a man in a motorised wheelchair in the back nine times.

The man in the wheelchair did not survive in the incident which took place in the city of Tucson, in the US state of Arizona on 29th November.

The first piece of footage, which are images from the police officers body cam, shows the officer arriving at the scene and getting out of his vehicle.

The police officer runs over to the man in the wheelchair while someone can be heard shouting in the background “you need to stop”.

The man in the wheelchair, named by police as Richard Lee Richards, 61, can be seen sitting in the red, motorised wheelchair and appears to be attempting to enter a store.

Another police officer, sporting a beard, can be seen standing to the left of the man in the wheelchair. The other police officer shouts: “You’re not going into the store, sir.”

The suspect is asked to refrain from trying to enter the store. When the motorised wheelchair does not stop, the other police officer, who can be seen standing to the left of the suspect and sporting a beard, draws his firearm and opens fire multiple times.

The suspect then slumps onto the ground as the footage ends.

A second piece of footage shows the same incident from the angle of a security camera at the entrance to the shop.

The wheelchair can be seen moving towards the entrance to the shop when the bearded police officer draws his firearm and repeatedly fires at the suspect.

After slumping onto the ground, the bearded police officer can be seen handcuffing the motionless suspect.

The audio track then indicates that medics were called to the scene but the wheelchair-bound man was pronounced dead at the scene.

The Tucson Police Department shared images of the incident online and said: “Detectives are investigating an officer-involved shooting in the parking lot of 1800 W. Valencia Rd. The incident occurred just before 6 p.m. Additional updates to follow.”

They later announced that the bearded officer who opened fire on Richards, and who they named as Officer Ryan Remington, was being fired for excessive use of force.

Tucson Police Chief Chris Magnus said he was “deeply disturbed and troubled” by the footage and the case is currently being reviewed by the Pima County Attorney’s Office.

Magnus said: “His use of deadly force in this incident is a clear violation of department policy and directly contradicts multiple aspects of our use of force and training.”
