The accident happened at Scapa Flow in Orkney
A female diver who died at Scapa Flow in Orkney has been named as a 52-year-old teacher who was on a school trip.
Janet A'Lee, from Tiverton, Devon, died on Monday. She was with her partner on a diving trip which included pupils from the school where they both worked.
The Blundell's teacher was diving with one of the senior male pupils.
When she resurfaced she was in difficulty and fell unconscious. She later died. The Health and Safety Executive has been informed.
Blundell's headmaster Ian Davenport said of the learning support teacher in a statement on the school website: "It is with great sadness that I can confirm that the school has been informed by police in Scotland that a member of school staff, Janet A'Lee, died in a tragic diving incident on Monday morning.
"This is a tragedy for Janet's family and friends and our thoughts and prayers are very much with them. The police have confirmed that all the other members of the party, staff and pupils, are safe and well.
"Janet was a very experienced and highly qualified diver and a popular and respected member of staff. This awful accident is the subject of a police investigation and we will be co-operating fully in any way we can."
He added: "We are now taking steps to ensure the safe return of the other members of the party and to offer full support and counselling to all those close to the tragedy."
And Mr Davenport later told BBC Scotland: "She was a wonderful person and will be sorely missed."
A member of staff was flying to Orkney to offer support.
There were seven in the diving party.
