LOUISVILLE, Ky. (WDRB) -- Justin Bieber has turned himself in to police for assault charges.

The 19-year-old arrived in a black SUV wearing a winter coat and a backwards ball cap before being led through a throng of police and reporters.

A police official said the charge related to an alleged assault on a limo driver in December.

He has already pleaded not guilty in Florida to DUI after drag racing through the streets of Miami Beach.

Bieber is still under investigation for felony vandalism in Los Angeles County over egging his neighbor's home.
