Banksy has landed a top documentary award - and immediately covered the trophy with graffiti.
The street artist was rewarded with a prize at the British Documentary Awards, presented by the Grierson Trust.
And during a taped acceptance speech he held up his statuette to show he had added his own personal touch - by spray-painting the eyes and cheeks.
The secretive artist's film Exit Through The Gift Shop was named most entertaining documentary at the annual awards, which took place at the BFI Southbank in London.
The jury panel said the film was "original and insightful".
Banksy joked: "This is a very proud moment for me. I've always dreamt of winning a Grierson Award ever since I first heard about them two weeks ago."
The artist, who hides his identity, continued: "I do like to think that in this world of graffiti art - which is essentially mindless, messy and stupid - we finally gave it the kind of documentary it deserves.
"I've always been considered a bit of an anomaly in the graffiti community - probably because I use words like anomaly. So I'd like to dedicate this award to all the real graffiti writers out there, the ones risking life and limb every night who never get any kind of recognition. Well, other than having their name written in huge letters on every available surface all over town."
The awards, hosted by broadcaster Sandi Toksvig, also recognised filmmakers such as Julien Temple and Mat Whitecross.
Director Temple - whose credits include The Great Rock And Roll Swindle - took the best historical documentary prize. And Whitecross, who first made his mark making Coldplay videos before the Ian Dury Biopic Sex & Drugs & Rock & Roll, took the title for the best film about a contemporary issue with Moving To Mars.
