Swaleside opened in 1988 with four residential wings (A-D), each holding 126 prisoners. E wing, a purpose-built drug treatment unit opened in 1998, with a holding capacity of 120 prisoners. In 1999 F wing opened, also designed to hold 120 prisoners. A further two wings were added, G wing in 2009 and H wing in 2010, each with a 179 holding capacity. The prison also has a 25-bed segregation unit and a 17-bed inpatient health care unit. In April 2006, a prison officer from Swaleside was jailed for two years, after he tried to smuggle
cannabis into the prison. The officer (who is the son of a prison governor) had been discovered as he reported for his shift during a routine search. Two months later, an inspection report from
Her Majesty's Chief Inspector of Prisons praised Swaleside Prison for its "greatly improved living conditions and atmosphere." The report also stated that relations between staff and prisoners were good and security was well-managed. However the prison was told to increase employment places and training programmes for prisoners, as well as improve anti-bullying and
race relations strategies. In October 2014, The
Prison Officers Association said a major incident had happened at the jail and a prison officer had been stabbed during a riot,
Mike Rolfe told the
BBC a prison officer had been injured and he said a disturbance began at the jail during the afternoon and was still ongoing. The officer was taken to hospital to treat facial injuries but had since been discharged. In March 2015, a prisoner was murdered by two fellow inmates. A Kent Police spokesman said: "The Kent and Essex Serious Crime Directorate has launched a murder investigation after a man was pronounced dead in HMP Swaleside at around 7pm on Wednesday 25 March. Two men, aged 32 and 44, have been arrested on suspicion of murder and remain in police custody." ==The prison today==
