TORONTO (AP) -- A police official says Justin Bieber is expected to turn himself in to face an assault charge in Toronto.
The official said the charge has to do with an alleged assault on a limo driver in December. The official spoke Wednesday evening on condition of anonymity because they were not authorized to speak publicly.
Toronto police said in late December they were looking into allegations that a member of Bieber's entourage assaulted a limo driver who was driving the Canadian pop star and several others. Police said at the time that it was unclear whether Bieber was involved.
A spokesman for Bieber had no comment Wednesday.
Earlier Wednesday, the baby-faced 19-year-old pleaded not guilty in Florida to charges of driving under the influence after driving nearly twice the speed limit on a Miami Beach street. He also pleaded not guilty to resisting arrest and driving with an expired license.
Bieber also remains under investigation for felony vandalism in Los Angeles County over an egg-tossing episode that damaged his neighbor's home. Detectives searched his home on Jan. 14, and prosecutors have sought additional information before determining whether to pursue charges.
The arrest and investigation, and now the Canada case, have brought Bieber more attention than the recent release of his latest album. Its reception has been far from the chart-topping success Bieber had after he debuted in 2009, with multiple platinum albums.
Last year, Bieber made headlines for everything from clashing with a paparazzo to fainting at a show to being photographed smoking marijuana. German authorities charged him thousands of dollars after he abandoned a pet monkey that they seized from him for failing to have proper vaccination papers.
The singer also had to apologize to Bill Clinton after cursing the former president and spraying his photo with cleaning fluid in a New York City restaurant kitchen.
