Riot police were called in to quell protests by angry refugees, detained in an immigration removal centre in Lincolnshire, after the death of a 26 year old Bangladeshi man.
Rubel Ahmed died on Friday night and the Home Office told the family he committed suicide, however fellow detainees told reporters that he had been complaining of chest pains for over an hour, without receiving medical attention. His family have called for an independent inquiry into his death.
The Home Office is said to be investigating the disturbances at Morton Hall, which saw guards withdrawing to a "place of safety", after around 30 men refused to go into their rooms.
A Tornado team, usually used in prison riots, entered the facilities armed with batons, to quell the protests on Saturday evening, the Daily Mirror reported.
A Home Office spokesman said at the time: "A disturbance involving a number of detainees is currently ongoing at Morton Hall IRC.
"Specially trained staff have been deployed to bring the situation to a safe conclusion. There are no reported injuries to staff or detainees relating to this incident."
The immigration removal centre is run by the Prison Service on behalf of the UK Border Agency.
