According to TMZ
Justin Bieber was bum rushed in a Canadian club by an over willing partier who tried in vain to tackle him.
Everything went down at 3 am yesterday at a Toronto club. Sources on scene let us know JB left his sheltered VIP area to mingle with the regular folk - and that is the point at which a male clubgoer charged at him, got hold of his shirt (which he was wearing) and endeavored to bring him down, yet came up short.
In the pics ... you can see security rushed in stat (above) and managed to pull the guy off Bieber -- successfully taking him to the ground. In the midst of the chaos we're told JB was seen trying to defend himself, unleashing a fury of kicks.
The attacker was escorted out of he club. Police were never called.
JB and his crew also made a hasty retreat.
