Footage of Justin Bieber appearing to sway and stumble as he attempts to walk in a straight line for a sobriety test has emerged.
The film was shot at a south Florida police station following his DUI arrest in Miami Beach in January and reveals the 19-year-old singer decked out in cherry red trainers, with a hoodie pulled over his head.
Further footage (below) shows him alone in a cell - with his hoodie still up - pacing, before dropping to the ground to do pushups.

Miami-Dade County prosecutors are said to have released 10 hours of film on Wednesday, though much of it does not feature Bieber.
Bieber's lawyers are said to have successfully persuaded a judge not to release footage of the singer urinating into a cup.
The Canadian-born performer, who turns 20 this weekend, has pleaded not guilty to driving under the influence, resisting arrest and invalid-license charges.
