The clip shows four prisoners apparently posing inside a cell at Ford open prison near Arundel with dance music blaring while being filmed by a fourth man.
One prisoner in a tracksuit appears to be swigging from a glass with a large wine-type bottle in his hand, while another is on a phone with a can of drink in his hand.
