A Colorado police officer in the United States has been arrested after being filmed threatening to kill a man during an arrest.

Body camera footage shows Aurora policeman John Haubert using a pistol to strike the man, saying “if you move, I will shoot you”.

The arrest comes amid intense scrutiny of police misconduct in the US following the 2020 death of George Floyd, which sparked national protests.

A second officer has also been arrested for failing to stop Haubert.

Footage shows Haubert repeatedly saying “stop fighting” as the man tells him he can’t even breathe.
