The 18-year-old Canadian singer was not in the car when the accident took place yesterday. He had reportedly loaned out the car to a friend.
The car was pulled over by California Highway Patrol for a routine traffic stop in Los Angeles, TMZ reported.
The photographer, who was following the car, was attempted to take pictures as the car stopped until officers advised him to move back because the situation was unsafe. He was then struck by another car and killed.
The identity of the photographer is yet to be revealed. LAPD is currently investigating the accident on the scene.
