Four other people were rescued from the lake between High Eske Nature Reserve and Pulfin Bog Nature Reserve, Tickton, on Wednesday night.

Police and fire crews were called to the emergency at around 7pm.

Humberside Fire and Rescue Service said "tragically the incident resulted in two young people losing their lives".

A statement from the service said: "Our thoughts and deepest sympathies are with the families and friends at this difficult time.

"Crews from Humberside Fire and Rescue Service, Humberside Police, and Yorkshire Ambulance Service were in attendance and worked together.

"A further four members of the public were rescued from the reserve by Humberside Fire and Rescue Service using a boat and Humberside Police deployed diving teams."

The area was closed on Thursday as police and the fire service continued to investigate what happened.

Warning about dangers of open water

The tragedy also prompted Humberside Fire and Rescue Service to issue a warning about the dangers of open water.

"The service would like to stress the importance of remaining safe around open water and the clear advice from the emergency services is that people should not enter the water," a spokesperson said.

"Open water such as ponds, rivers and lakes etc are highly dangerous and people should not enter them."

It comes after 16-year-old Tyler Wilson drowned in the River Calder near Castleford in West Yorkshire after getting into trouble in the water.

Earlier this month a teenage boy also died after being pulled from the River Soar in Leicestershire.
