Police said the youngster was pulled from the swimming pool at Bicclescombe Grange near Ilfracombe on Friday at around 4.30pm.

The owners of the hotel, who were away at the time of the accident, said the Health and Safety Executive has examined the pool and found nothing untoward.
A police spokesman has said this is a very tragic incident and the circumstances are not known at this time but there is nothing to suggest this is suspicious.

This is a terrible tragedy and my understanding is that this is a tragic accident.
All our thoughts are with the family at this very difficult time."
