A fearless police officer has been hailed a hero after dramatically pulling one of the suspected Christchurch mosque shooters from a car during a dramatic roadside arrest.
Footage filmed by a passing motorist shows the gunman's white station wagon wedged between the gutter and another police car, with its front wheels spinning in the air.
The suspect is still inside the car as the two officer's approached the car with their weapons drawn - knowing the suspect would have been carrying multiple high-powered weapons.
