Two women have died following an incident at the Eryri national park, also known as Snowdonia, in Wales, police said. North Wales Police said the incident happened on Wednesday night.
The force were called to the scene at 9.31pm on June 11 after receiving reports that one woman had been pulled from a pool close to the Watkin Path in Nant Gwynant, Gwynedd, while another female was still in the water. The Llanberis Mountain Rescue Team were dispatched to the area along with North Wales Police, the Air Ambulance and the Coastguard Rescue Helicopter.
The second woman was pulled from the water, however, despite the best efforts of all involved both were pronounced dead at the scene, the force said.
Detective Chief Inspector Andy Gibson of North Wales Police said: "Our thoughts and sympathies remain with the families and friends of both women."
An investigation into the incident has been launched, he added, as he asked people with information to come forward.
He said: "An investigation to establish what happened is now underway.
"We are appealing for anyone who may have been walking in or around the Watkin Path area between 6pm and 9pm last night, they are urged to contact us via the website or by calling 101 quoting reference number 25000480868."
The coroner has been informed.
