A 14-year-old boy is missing and believed to have drowned after getting into difficulty in the River Thames in Richmond, southwest London, on the UK’s hottest day of the year.
It comes as four other people have died while swimming in open water during the current heatwave as Britain swelters, with temperatures reaching 38.1C (100.58F) today, the third hottest day on record, and they may hit 41C (105.8F) tomorrow.
The UK Health Security Agency has issued a level 4 heat-health alert – described as an “national emergency” – and the UK is under its first red extreme heat warning for a large part of England, issued by the Met Office.
The Metropolitan Police said officers were alerted just before 5pm by the London Ambulance Service to reports a child was seen entering the water at Tagg’s Island in Hampton.
A widespread search was carried out involving police, paramedics and fire crews, as well as members of the public.
The Met said: “Very sadly, efforts to locate the boy were unsuccessful and at 6.40pm, the rescue operation was brought to an end. Efforts to recover his body will continue into this evening.”
Superintendent Richard Smith, from the South West Command Unit, said: “Despite the very best efforts of all involved, we must now sadly conclude that this young boy has died.

“I know that on days like today when temperatures are at a record high, it might look appealing to jump in and cool off in rivers, reservoirs, lakes or other open water.
“Please don’t. The dangers are real and this evening in Richmond we have seen the terrible consequences of what happens when it goes wrong.”
Meanwhile, the family of a “kind and loving” 13-year-old boy who died after getting into trouble while swimming in a Northumberland river say they are “absolutely devastated”.
Robert Hattersley, from Crawcrook, lost his life following an incident in the River Tyne near Ovingham on Sunday.
His family said in a statement: “It is impossible to put into words the heartbreak we are feeling – Robert was so kind and loving. We are absolutely devastated by what has happened.
“He brought a smile to so many people’s faces and he will be missed by absolutely everyone who knew and loved him.”
Detective Inspector Phil Hughes, of Leeds CID, said: “This incident serves as a timely reminder about the dangers of swimming in open water.”

Also, a 16-year-old boy died after getting into difficulty earlier today in Bray Lake, near Maidenhead, in Berkshire.
Superintendent Michael Greenwood, the local policing area commander for Windsor and Maidenhead, said it was an “absolute tragedy”.
Emergency services have issued urgent appeals for people to stay out of dangerous waterways and reservoirs.

Temperatures rose to 38.1C in Santon Downham, Suffolk today, and the mercury topped 37C in a number of other places.
