A video of Justin Bieber made at a south Florida police station after his arrest last month shows him walking unsteadily during a sobriety test.
Miami-Dade County prosecutors released about ten hours of video yesterday, only a few moments of which depicted the singer.
In one clip, Bieber wavers as he tries to walk heel to toe, then stumbles slightly as he turns and looks to have his arms out for balance. The video was sought by media under Florida's public records law.
Lawyers for the 19-year-old persuaded a judge to withhold four clips depicting him urinating in a cup for a drug test.
Bieber has pleaded not guilty to driving under the influence, resisting arrest and invalid licence charges after his January 23 arrest.
Meanwhile, a security guard for the singer faces a robbery charge in Georgia after he admitted taking a photographer's camera.
Hugo Hesny (32) faces a robbery by snatch charge. Photographer Jason Winslow called police to report that his camera had been taken.
Mr Winslow told police Hesny confronted him as he took photos from the car park of the Sandy Springs Funhouse arcade.
Mr Winslow said Hesny chased him as he drove away, cut him off, opened his vehicle door and took his camera. Police say Hesny denied taking the camera but later said he took it to delete the photos.
