Three people have been found dead and four people have been taken to hospital after an incident at a Dorset care home, police said.
Emergency services are at the scene at the Gainsborough Care Home in Ulwell Road in Swanage, with the remaining residents having been evacuated to a safe location.
Dorset Police said the deaths are being treated as unexplained, with an investigation launched, but Gary Suttle, from Dorset Council, told the PA news agency there is a “suspicion” that “this could be attributable to carbon monoxide but it has not been proven”.
