The popstar allegedly pinned a photographer between his white Ferrari and a parked Audi, then drove away before the LAPD could arrive to take down a report.
The photographer was taken to Cedar-Sinai Medical Center in Los Angeles for treatment, and the police continued their investigation from the emergency room.
Accident: Justin
Bieber has been allegedly involved in a hit and run on Sunset Boulevard,
which sent a photographer to hospital
One of Bieber's bodyguards allegedly pulled up in his white sports car, then jumped out of the driver's seat to make way for his teenage boss who crawled behind the steering wheel from the right side, passenger door.
Lil Twist jumped in next to Justin, who waited as the popstar motioned for the gathered paparazzi to move out of the way so he could drive through.
Victim: A photographer was taken away in an ambulance after the collision on Monday night
Painful: Emergency response units arrived after Justin had already reportedly left the scene
The scene: Justin was leaving Laugh Factory in Hollywood with his best friend Lil Twist
The impact reportedly caused the pap to be trapped briefly between the two cars, but it would seem Justin did not drive off straight away, as the victim's camera can still be seen resting on the Ferrari's bonnet as he limped off in pain.
It is unknown if Justin knew the paparazzo had claimed to be hit, as the collision occurred on the opposite side to the driver's seat, so would not be in his best line of vision.

Emergency response units - including the fire department and police - arrived on the scene shortly after Bieber's alleged exit, and they took the photographer to the same hospital where Kim Kardashian gave birth to her baby daughter.
TMZ report that the LAPD is reaching out to Bieber and his representatives.

In April, Swedish police found a small amount of drugs on Bieber's tour bus driving away from Stockholm hotel, while he managed to cause outrage by leaving a 'tasteless' comment in the guestbook at the Anne Frank House in Amsterdam.
He has also recently been dumped again by his long-term girlfriend Selena Gomez, and insulted her further by partying with her known rival Miley Cyrus.
No doubt Justin will be hoping 2014 comes around pretty quickly.
