AceShowbiz - Teen pop sensation Justin Bieber has offered his support to his manager, who turned himself into police on Wednesday, March 24 to face charges relating to the singer's chaotic appearance at a shopping mall in New York in November 2009. The 16-year-old was forced to cancel a signing appearance at the Roosevelt Field mall after thousands of fans descended on the venue - overwhelming security teams and police. One young girl was hospitalized in the chaos.

After the incident, the singer claimed he and several associates had been threatened with arrest unless he sent out an internet message to fans using his Twitter page, informing them the event had been canceled and urging them to go home. Bieber's manager, Scott 'Scooter' Braun, has now surrendered to police to answer misdemeanor charges of reckless endangerment and criminal nuisance - after he allegedly refused to cancel the event.

And the "Baby" hitmaker is determined to stand by his manager. He donned a "Free Scooter" T-shirt during an appearance in Chicago, Illinois on Wednesday, March 24 - and sent his troubled svengali a message of support on his Twitter page.

Bieber writes, "You've got my total support (Scooter Braun). Wish you were here in Chicago with us. FreeScooter." Braun has pleaded not guilty to charges of reckless endangerment, criminal nuisance and endangering the welfare of a child. He faces a year in jail if convicted.
