Pop star Justin Bieber was left shaken on Saturday (31Aug13) after he was attacked during a night out in Canada.

The Baby hitmaker was hanging out at a club in Toronto when he left the venue's Vip area to mingle with the crowd, but he was soon rushed by a male partygoer.

Editors at Tmz.com have obtained pictures of the altercation, with images showing a shocked Bieber looking on as his security guards grapple with the man.

The unidentified suspect was then escorted out of the club, with Bieber leaving shortly afterwards.

The incident comes after a troubled few months for Bieber, who has been accused of urinating in a restaurant mop bucket, spitting at a Dj, fighting with photographers, showing up late for concerts and driving his sports cars around his Calabasas, California neighbourhood at high speeds.
