Los Angeles police Officer James Stoughton says the man died at a hospital Tuesday evening.
Stoughton says Bieber was not in the car at the time. Sgt. Rudy Lopez told theLos Angeles Times that the pop star's friend was driving the car when it was pulled over for a traffic stop.
It was parked on a busy street when the photographer arrived. Police say the man was struck by a car as he returned to his own car.
Stoughton says no charges are expected against the motorist who hit the man.
A call to a Bieber publicist was not immediately returned.
