Boy's body found in river at Walton-on-Thames
The body of a 15-year-old boy has been recovered from the River Thames in Surrey.
The youngster was swimming with friends at Walton-on-Thames when he got into difficulties at about 14:20 BST.
Police sent a helicopter and specialist divers to Felix Road recreation ground.
Sue Chambers, who lives opposite, tweeted: "Children having fun turned into tragedy."
In a statement, Surrey police said: "The body was recovered from the river around 16:40 BST. The boy's next of kin has been informed.
"Enquiries remain ongoing... but it is not believed to be suspicious or that there is any third party involvement at this time."
Early years consultant Ms Chambers said: "It was a dreadful affair. It was right opposite our house.
"There were some kids swimming where they often do. Then the others were shouting and that was when we were first alerted."
Her husband Alan James, 73, a French polisher, told the BBC he took the emergency services out on his boat.
He said the boys were aged about 13 or 14.
"I have got a boat which has got a sonar on it. When the firefighters and police got here I pointed out that I had a sonar on my boat so I took them out on it.
"Unfortunately we then found the body. It's not usually dangerous there. It's really sad."
