A police video has been released of Justin Bieber walking unsteadily as he took a sobriety test after being held on suspicion of driving under the influence and resisting arrest.
In the two-minute clip at a police station, 19-year-old Bieber tries to walk in a straight line heel to toe and appears to stumble slightly after he turns around.
The Canadian pop star and R&B singer Khalil Amir Sharieff were detained on January 23 in Miami Beach during what police described as an illegal street drag race between a Lamborghini and a Ferrari.
Neither has been charged with drag racing, but Bieber tested positive for marijuana and Xanax - a drug which is usually used to treat anxiety disorders.
The video was released by Miami-Dade County prosecutors following requests from the media in the US.
Several clips were withheld at the request of Bieber's lawyers, including four segments depicting the singer urinating into a cup for a drug test.
Miami-Dade County Judge William Altfield will review those clips and plans another hearing next week on whether they will be released.
Earlier this month, police released a video showing Bieber taking off his clothes and being searched by an official after his arrest in Florida.
The singer has pleaded not guilty to driving under the influence and resisting arrest.
