A teenage girl was fighting for her life today after being pulled from a lake at a water park.
The 15-year-old, from Middlesex, was playing in the lake at Cotswold Water Park at 3.45pm on Sunday when her parents lost sight of her.
A boy playing with a football in the lake is believed to have pulled her out of the water and a lifeguard then carried out cardiopulmonary resuscitation (CPR) until paramedics arrived, Gloucestershire Police said.
The girl was taken to Great Western Hospital in Swindon, Wiltshire, where she was in a "critical" condition in intensive care today.
Cotswold Water Park covers 140 lakes, set in 40 square miles of countryside.
The girl was playing in a part of the water park called the Cotswold Country Park and Beach in Ashton Keynes, Wilts.
Officers urged the young man who helped save her to contact them on 0845 090 1234.
