Police asked prosecutors to consider filing a misdemeanor battery charge against the pop star, but Los Angeles County sheriff's investigators found no visible injuries, footage or photos to confirm allegations by the photographer.
Bieber was leaving a movie theater in Calabasas with then-girlfriend Selena Gomez on May 27 when he encountered a photographer in a parking lot and some kind of altercation ensued.
Investigators say a doctor found only superficial injuries, and deputies observed no injuries on the photographer after the incident.
Officials interviewed several witnesses, but none reported seeing Bieber kick the man, and they said the photographer kept taking photos as the two singers left the location, according to the charge evaluation worksheet prepared by the district attorney's office.
According to the document, investigators reviewed all of the photographs taken during the incident by many surrounding photographers. They didn't find any photos indicating a physical altercation.
