A firefighter from Suffolk has died during a training exercise at an Olympics watersports venue.
Alan Soards, 38, from Lowestoft, was taken ill in the water at the Lee Valley White Water Centre in Waltham Cross, Hertfordshire, on Tuesday. Three ambulances and two air ambulances were called at about 11.30am, but attempts to resuscitate Mr Soards failed.
A spokesman for Suffolk Fire Service said Mr Soards had been a firefighter for 11 years and had no history of medical issues. He was on a water rescue training course with colleagues from Lowestoft and Norfolk.
Andy Fry, Chief Fire Officer at Suffolk Fire and Rescue Service, said: "Despite valiant attempts, his firefighter colleagues and paramedics were unable to save his life.
Mr Soards served on White Watch at Lowestoft South fire station.
"He was highly regarded by his colleagues - he was an experienced, extremely professional and capable firefighter," said Mr Fry.
"He loved his job and was well-respected by those who worked with him, many of whom also considered Alan to be a close friend. I want to pay tribute to the firefighters from both Suffolk and Norfolk who were with Alan yesterday and to our colleagues in the other emergency services who fought so hard to save his life."
He added that the fire service was working with Hertfordshire Police and the Health and Safety Executive to establish the full details of Mr Soards's "untimely death".
