Australian police have launched an internal investigation after singer Lily Allen posted a photograph of herself being handcuffed after she stepped off a flight in an apparent prank gone wrong.
Allen, who has been touring Australia, landed at Gold Coast Airport in Queensland ahead of her appearance at the Splendour In The Grass festival on Sunday, where she was greeted by a handful of fans and a number of Federal Police officers.
Breaking strict protocol, the officers agreed to Allen's request to be put in handcuffs as she knelt down - and an aide took a photograph and posted it on her Twitter account which has more than 4.7 million followers.
The image has since been removed.
