A woman has been released under investigation after being arrested over the deaths of three people at a care home in Dorset.
The 60-year-old was arrested last night on suspicion of manslaughter.
Dorset Police said detectives are still exploring possible carbon monoxide poisoning as the primary line of enquiry.
The deaths of the three residents – two men aged 74 and 91 and an 86-year-old woman – at Gainsborough Care Home in Ulwell Road, Swanage, on Wednesday are being treated as unexplained.
Their families are being updated with any developments as the investigation progresses, police said.
The woman was arrested “to establish whether there were any actions or omissions that are believed to be grossly negligent”, the police force said on Thursday, and enquiries will continue into this.
Detective Chief Inspector Neil Third said: “The thoughts of the investigation team and wider force remain with the loved ones of those who tragically died.
