The 18-year-old 'Baby' hitmaker was travelling in his Fisker Karma hybrid sedan here when a cop pulled him over after spotting another vehicle trailing him, reported TMZ online.
The snappers rushed to the scene to get a shot of Bieber, who was explaining to the officer that the vehicle following him was part of his security team.
Two photographers are said to have lost control of their cars and smashed into one another, but the singer managed to avoid being caught up in the accident. No arrests have been made.
