Detectives investigating the full circumstances surrounding the deaths of three residents at a care home in Swanage have made an arrest.

Dorset Police received a report at 7.16am on Wednesday 23 October 2024 regarding three residents who had been found deceased at the Gainsborough Care Home in Ulwell Road.

Officers attended the care home, alongside colleagues from Dorset & Wiltshire Fire and Rescue Service and South Western Ambulance Service.

Seven people have been taken to hospital as a precaution and other residents of the address were evacuated to a location where they can receive appropriate care. They are being supported by Dorset Council and the health service.

The deaths are currently being treated as unexplained. A significant multi-agency presence will remain in the area – including a police cordon – as officers work alongside partners to carry out their investigations.

Detectives have confirmed that possible carbon monoxide poisoning is the primary line of enquiry. There is nothing to indicate any current risk to the wider public.

On Wednesday evening, a 60-year-old local woman was arrested on suspicion of manslaughter. She remains in police custody at this time.

Detective Chief Inspector Neil Third, of the Major Crime Investigation Team, said: “Our heartfelt thoughts and condolences are with the families and loved ones of those who tragically died and they are being supported by officers.

“As part of our investigation, we have made one arrest to enable us to establish whether there have been actions or omissions which are grossly negligent and gather as much information as we can about what has happened. It is important to note that the arrest process also provides certain legal protection to individuals and I would ask for the media and public to avoid speculating any further now that legal proceedings are active.

“We know that the residents of Swanage will be feeling the impact of this incident immensely and we would like to thank everyone for the care and respect that has been shown throughout the day.

“Our local neighbourhood policing team will be on hand to provide support – we know this is a difficult time and we are doing all we can to minimise the impact on the community while we conduct enquiries in the area.”
