Four people were shot and wounded early Saturday after a fight broke out outside a Los Angeles restaurant hosting a party that followed a Justin Bieber concert, police said.

The gunfire erupted outside The Nice Guy restaurant, striking and injuring four men ages 60, 19, 20 and 22, LAPD Officer Lizeth Lomeli said. Their names were not released.

Two of the victims were taken to the hospital and were listed in stable condition. A third person left the scene but was later transported by the Los Angeles Fire Department to the hospital, also in stable condition, she said.

Lomeli said she didn’t have immediate information on the fourth victim.
