Video of Justin Bieber made at a south Florida police station after his January arrest shows him walking unsteadily during a sobriety test.
Miami-Dade County prosecutors released about 10 hours of video on Wednesday, 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 appears to have his arms out for balance.
The video was sought by the Associated Press and other media organisations 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 following his January 23 arrest.
