Golden Bear for Elite Squad
For many, the film was a surprise winner over the hotly-tipped oil-and-religion epic There Will Be Blood, which stars Daniel Day-Lewis and Little Miss Sunshine's Paul Dano.
Elite Squad has caused a sensation in Brazil, with its portrayal of a violent police unit willing to torture and kill in their battle against the country's drug lords and widespread internal corruption. Around 11.5 million people in Brazil have reportedly seen the film on pirated DVD.
In other awards, the Silver Bear for the Jury Grand Prix went to Standard Operating Procedure by Errol Morris, a documentary looking at torture and abuse at Abu Ghraib prison in Iraq.
Best director went to Paul Thomas Anderson for There Will Be Blood, while Iranian performer Reza Najie took the best actor prize.
British actress Sally Hawkins, whose credits include Little Britain, Tipping The Velvet and gangster flick Layer Cake, took the Silver Bear for best actress for her performance in Mike Leigh's Happy-Go-Lucky.
Overall, 21 films were in competition at this year's festival.
