Rescuers have found the dead body of six-year-old Lucas Dobson, who slipped into the river while out fishing with his dad.
The schoolboy went missing in the River Stour in Sandwich, Kent on Saturday afternoon.
His father Nathan and two adults jumped into the water in an attempt to rescue him but he was swept away by a huge current.
Kent Police have now formally identified Lucas after finding a body in the river at 9.15am this morning.
Chief inspector Mark Weller said: ‘It brings an end to our search and I would like to echo Lucas’ family’s message of thanks to those who came out to help search for him in the last few days.
‘The community support we have witnessed has been heart-warming, even in the most tragic of circumstances.
‘While the search may have ended, our support to Lucas’ family continues.’
Emergency services experts used specialist equipment to find Lucas, including sonar detectors, underwater cameras, divers, dogs and drones.
More than 200 volunteers helped in the hunt including people from outside the county.
But they were later urged by police to ‘stay away’ when the river became the ‘sole focus’ in the hunt.
Vigils were held in towns across the south east of England for the missing schoolboy on Monday.
Twitter users shared images of lit candles under the hashtag #LightUpTheCoastForLucas in solidarity with his family.
The death is not being treated as suspicious, and a report is being prepared for the coroner, Kent Police said.
