During an event celebrating the launch of his new perfume at Macy's in Herald Square in New York, Justin Bieber was attacked by a crazed fan. Trouble in Teenland! The video above apparently shows the attack.

According to ABC:

Bieber who was attending an event inside Macy's unveiling his new cologne, decided to go outside of the store to acknowledge the fans that could not come inside to the event.

Witnesses say when Justing Bieber came out the doors an unidentified man jumped a barrier and knocked the teen sensation to the ground.

Bieber was not injured but appeared to be very 'shaken up'.

The man will now be taken to an undisclosed location and trampled to death by one-hundred angry tweens.
