Not everyone was impressed with the Bieber fever that swept Sydney when the Canadian pop star arrived for his long-awaited concert last week.

A Bondi Junction teenager has been charged by police after he allegedly broke into the roof of Acer Arena to throw eggs at Justin Bieber during his performance on Friday night.

A number of eggs were thrown at the teen heartthrob and his back-up singers during the performance, but all missed.

Acer Arena complained to police after becoming aware of the incident when details were posted on a social networking site.
