Gangnam-style police help charity
Cannot play media. Sorry, this media is not available in your territory.
A police officer in Cornwall has persuaded his colleagues to make a "Gangnam-style" video, in order to help raise funds for a boy, from Bury, Greater Manchester, who has a brain tumour.
Josh Wislon, whose first tumour developed when he was three, loves the emergency services and Sgt Gary Watts came up with the idea for the video after finding out via Twitter that the family was raising money to buy equipment for him.
