An underwater search for a former university lecturer feared dead after a boat carrying six passengers capsized has been called off.
Three women and one man, described as being in their 50s and 60s, were rescued and taken to hospital with minor injuries after the incident in the River Thames, near Shepperton, Surrey, on Sunday evening.
The body of Keith Lowde, 66, was found in the river by police divers on Monday, close to where the boat overturned. The body of his friend, former Cambridge University lecturer Rex Walford, has yet to be found.
A spokesman for Surrey Police said a thorough and extensive search by its specialist dive teams over the past two days had been unable to locate the missing man.
The decision to stand the underwater search down was based on a number of factors including visibility and currents in the water, along with the substantial area of water involved in the search operation, he said.
Instead, crews from Surrey Fire and Rescue Service will continue to search the water's surface.
Mr Lowde's family released a statement in which they spoke of their devastation at his loss. It said: "He was a wonderful husband and a truly amazing father. This tragic accident has left a massive hole in all our lives.
"The response from all our friends, Keith's work colleagues and his students has been immense and we thank them all for their support and help.
"It is clear that over his life Keith has helped so many people in such a positive way. He will be sadly missed but never forgotten."
Mr Lowde is believed to have been taking his wife and two other couples a short distance from his home on Pharaoh's Island in the River Thames to the bank at Shepperton.
