Two ambulance staff in England have been arrested as part of a major investigation into the deaths of six adults in Wiltshire.
Wiltshire Police confirmed that a man in his 30s from West Wiltshire was first arrested in June 2024 on suspicion of six counts of gross negligence manslaughter and four counts of ill-treatment or wilful neglect by a care worker.
A 59-year-old woman was arrested in March 2025 on suspicion of gross negligence manslaughter. Both worked for the South Western Ambulance Service and have since been released on bail.
Detective Chief Inspector Phil Walker of the force’s major crime team said: “We can confirm a major investigation is under way relating to several adult deaths in and around Wiltshire. Our focus is on supporting the families and loved ones of those who have died.”
The inquiry began in 2023 following initial concerns, with detailed investigations carried out before the arrests.
The South Western Ambulance Service said it launched an internal investigation immediately after concerns were raised and has worked closely with police since.
Both staff members were suspended from duty, with one no longer employed by the trust.
“This is an isolated situation and there is no ongoing risk to patients,” a spokesperson said. “We urge people to continue calling 999 in life-threatening emergencies.”
Gross negligence manslaughter applies when a breach of duty of care leads to an obvious and serious risk of death, according to the Crown Prosecution Service.
The South Western Ambulance Service, which covers large parts of southern England, was last inspected by the Care Quality Commission in 2022 and rated good overall, with outstanding care but requires improvement for emergency and urgent services.
