Two ambulance workers have been arrested over the deaths of six adults, Wiltshire Police have said.
The investigation was launched in 2023 and last year a manin his 30s, from West Wiltshire, was arrested 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 also arrested on suspicion of gross negligence manslaughter in March this year. Police have only released details of the investigation and arrests now.
Wiltshire Police said the two South Western Ambulance Service workers have been released on bail.
“We can confirm a major investigation is under way relating to several adult deaths in and around Wiltshire,” said Det Ch Insp Phil Walker from the force’s major crime team.
“This investigation has been ongoing since an initial report was made to Wiltshire Police in 2023 and detailed inquiries have been undertaken since to ascertain the facts,” he added.
