Officer Michael Slager stops Walter Scott's vehicle for a broken tail light moments before shooting him in the back. South Carolina officials have released a new video showing the moments before a US police officer fatally shot an unarmed man in the back.
The dash cam footage shows Walter Scott's car being pulled over and Officer Michael Slager asking for his paperwork.
After Mr Slager returns to his police vehicle, Scott opens his door and runs.
Mr Slager was arrested on murder charges after a video surfaced showing him shooting at Scott as he flees.
The newly released video shows Mr Slager pulling over Scott's Mercedes sedan due to a broken tail light, and asking for his drivers license and registration.


Scott explains that he is in the progress of purchasing the vehicle and does not have the correct paperwork with him.
Although the video does not capture Mr Slager firing eight shots, gunshots and shouting are heard off-screen.
"Get on the ground now!" Slager is heard shouting.
Mr Slager was fired on Wednesday from the North Charleston Police Department.
After video of Scott's death emerged, protesters chanted "no justice, no peace" outside the city hall on Wednesday, and they later held a candlelight vigil in honour of Scott.
They are the latest protests about police lethal force, which began after the killing of Michael Brown, a teenager in Ferguson by a police officer who was not charged for his death.
