A naturist swimming club is being investigated by the council after it began naked classes for children in a local swimming pool.

Ryedale Naturist Club, which holds fortnightly swims at Derwent Pool, near Malton, North Yorkshire, has come under scrutiny after it invited under 18s to swim in the nude with a parent or guardian.

Ryedale District Council, which owns the pool, has launched an investigation into whether there is a "risk to the welfare of children".

Lead councillor Luke Ives said: "While there is nothing wrong in the naturist club hiring the pool, it must be done in a way that does not give rise to any risk to children.

"I have asked that an urgent investigation takes place to ascertain the facts.

"If there is deemed to be any risk to the welfare of children, the council will not hesitate to take immediate action."
