Justin Bieber turns himself in to Toronto police

Troubled Canadian pop star Justin Bieber appeared at a Toronto police station Wednesday, reportedly to be charged for the December assault of a limousine driver, AFP reports. Wearing a baseball cap turned backwards and a black hooded winter coat, the singer entered the station in Toronto escorted by officers who rushed him through a large crowd of screaming fans and journalists. "Move back, don't push! Don't push!" a police officer said as girls shrieked at the sight of Bieber's large black limousine. CTV television said the heartthrob pulled up around 7:30 pm (0030 GMT Friday). In a chaotic scene, fans crushed in holding up smartphones hoping get a picture of the clean-cut, baby-faced young star turned tattooed, barely adult bad boy. A girl screamed "I love you, Justin, I love you!" as dozens of cameras flashed to light up the night. CTV television said Bieber was returning from a Toronto Maple Leafs hockey game on December 29 when police were called to intervene in an altercation with the driver of a limousine he used with his entourage. Toronto police, however, said they could not confirm reports that Bieber would be formally charged at the police station with the assault. "Duty Desk, 52 Division and Toronto Police Corp Comm cannot confirm any media reports about Justin Bieber, so please don't bother calling," Toronto Police tweeted. If confirmed, the charges would mark the latest run-in with the law for the 19-year-old after his Los Angeles home was searched because he allegedly hurled eggs at a neighbor's house, and his arrest in Miami Beach on January 23 for drag racing and impaired driving. He was released after posting a $2,500 bond. The singer also got in trouble with the authorities in Australia and Brazil for spraying graffiti. In Brazil, Bieber was photographed emerging under a blanket from a notorious Rio brothel and later tried in vain to bring prostitutes into the posh Copacabana Palace. Bieber said he was not guilty of the charges filed against him in Florida last week -- including drunk driving, resisting arrest and driving with an expired license. In a filing by the pop star's attorneys to a Miami court, Bieber formally rejected the charges. The White House, meanwhile, was asked to weigh in on Bieber's bad behavior after it received a petition with more than 100,000 signatures calling for the Canadian-born signer to be deported. By 9:00 pm Wednesday (0200 GMT Thursday), a petition on the White House website calling for the deportation of the Canadian-born teen idol had garnered more than 155,300 names -- easily surpassing the threshold of 100,000 signatures required for presidential consideration. "We the people of the United States feel that we are being wrongly represented in the world of pop culture," says the petition, created by one "J.A." in Detroit the day Bieber was busted in Miami Beach. "We would like to see the dangerous, reckless, destructive and drug-abusing Justin Bieber deported and his green card revoked. He is not only threatening the safety of our people but he is also a terrible influence on our nation's youth. We the people would like to remove Justin Bieber from our society." Bieber is understood to be living and working in the United States under a renewable O-1 visa for entertainers, rather than a green card for permanent resident status. It remains unclear whether Bieber's visa to stay in the United States would be affected by his legal issues.
