Footage has been leaked from inside HMP Swaleside taken by inmates during last night's riot which shows the drama unfolding.
The video shows a prisoner armed with snooker balls, and one man repeats "Swaleside is burning" as a hose is being sprayed.
Two masked men can also be seen with their faces towards the camera, as one gestures and says "welcome to Swaleside".

Kent Police has confirmed officers are investigating the riot.
A spokesman said: "Kent Police is continuing to liaise with Her Majesty’s Prison Service in relation to a disturbance at HMP Swaleside on the Isle of Sheppey on Thursday 22 December 2016.
"Detectives from Kent Police’s Prison Investigation Team will be carrying out enquiries to identify those responsible for criminal offences committed during the incident."
Up to 120 prisoners were involved in the disturbance, with 60 hardcore taking over the A Wing.
Fires were lit inside the building and emergency services were on the scene for several hours.
In the video, no prison guards appear to be seen.
The inmate with the 'illegal' mobile phone says "no face no case" as he films the floor.
The disturbance took around six hours to be brought back under control, ending at around 1am today.
The specialist Tornado Squad - a group of riot trained prison officers - had been called in with officers drafted in from across the South East.
Other prison staff from HMP Swaleside were sent home and it's been confirmed no one was hurt.
Dogs could be heard barking from inside at around 9pm.
The riot follows a major incident in Birmingham last week involving about 600 prisoners, described as the worst prison riot in 25 years.
Despite speculation on social media, the Ministry of Justice confirmed no prisoners were moved to HMP Swaleside from HMP Birmingham following last week's drama.
Speaking this morning, Sheppey MP Gordon Henderson said: "We have found that in the prison service, often when there is one outbreak, there are copycat incidents.
"This is a particular problem when prisoners have access to social media and newspapers. This incident was relatively low key, far from a 'riot'.
"Prisoners reacted to cells being searched when the authorities were looking for contraband.
"They [authorities] have every right to search cells and I'm pleased they took swift action to
bring the rebellion back into order. I don't think this will happen again.
"Lack of prison officers is also an issue, and one which I will continually raise, but I don't think this was because of a lack of prison officers."
