Supt Paul Butler, of Humberside Police, said: "Our thoughts and condolences are with both young men's families and loved ones at this very difficult and sad time.

"We are working together with all the relevant agencies, including Humberside Fire and Rescue, to fully understand the circumstances of the tragic accident."

The area has been closed to the public and an investigation was under way, the fire service said.

A Yorkshire Ambulance Service spokeswoman said "a number of resources" were sent to the scene.

Jon Henderson, an area manager for Humberside Fire and Rescue, said people should not enter open water such as ponds, rivers and lakes "regardless of how strong a swimmer you may consider yourself to be".

He added: "They are incredibly dangerous. They are incredibly cold, they have sheer drops, they have hidden obstacles underneath and quite often there are currents involved too."

A spokesperson for the Environment Agency, which owns the reserve, said: "We are deeply saddened to hear of the tragic deaths of two people at High Eske Nature Reserve. Our thoughts and deepest sympathies are with their family and friends. We are working with the appropriate authorities to assist in their investigations."

In a separate incident on Wednesday evening, a body believed to be that of a 16-year-old boy was recovered from the River Calder in Castleford, West Yorkshire.
