LAPD probes Bieber's scuffle with photog
Meanwhile, the Los Angeles County District Attorney's office said police have not referred the case there for prosecution.
"We have received no case," spokeswoman Sandi Gibbons told Newsday. TMZ and "Access Hollywood" both reported that the case was going to the district attorney's office.
Police have said they are investigating the altercation as a possible misdemeanor battery. If charged and convicted, Bieber would face 6 months in jail, said TMZ.
Due to chronic overcrowding in California jails, however, sentences are typically shortened.
Bieber confronted the photographer after he and his girlfriend, singer-actress Selena Gomez, 19, left a movie theater in Calabasas, Calif., the suburb where Bieber lives.
The photographer afterward called 911 complaining of chest pains, saying he had been "physically battered." Bieber and Gomez had departed by the time sheriff's deputies arrived. The unnamed photographer was treated and released at a hospital.
Bieber's representatives have not commented. Bieber, whose new single, "Die in Your Arms," dropped Tuesday, tweeted Monday that he was "gonna focus on the important stuff -- the music." The 18-year-old singer also tweeted that he was leaving the country to go on a promotional tour to Norway.
