The altercation took place at around 2:45 a.m. local time on the 400 block of N La Cienega Boulevard, the Los Angeles Police Department said.
Bieber hosted an after party at The Nice Guy restaurant and lounge, after a concert, and “the shooting took place … near The Nice Guy, but it wasn’t right outside the door,” a source familiar with the event to DailyExpertNews.
The source added that the musician had already left the party when the shooting happened.
Four people were shot, police said in their release. Two of the victims were taken to nearby hospitals by paramedics, while the other two were taken to hospitals themselves, police said.
“The incident is not gang-related,” police said earlier.
DailyExpertNews contacted Bieber’s publicist on Saturday, but has not heard back.
Restaurant The Nice Guy is owned by The h.wood Group, a catering company that owns several locations in the Los Angeles area. DailyExpertNews was unable to reach a representative for h.wood.
