A headteacher has spoken of her sorrow at the death of 12-year-old after his body was discovered in the River Cam.
Cambridgeshire Police and other emergency services launched a search after reports that the boy did not resurface after going into the river at Lammas Land, the Fen Causeway, on the outskirts of Cambridge at about 6pm on Tuesday.
The body of the boy, named locally as Andrew Collings who attended the city's Netherhall School, was recovered at about 3am.
Principal Caroline McKenney said: "The school extends its deepest condolences to Andy's family.
"When the time is right we will be speaking to his family and students at the school to find a suitable way of remembering him."
Donna and Andrew Frost, whose son Charlie had been playing with Andrew earlier in the evening, said they were devastated.
Mrs Frost said: "Apparently two or three others jumped in but couldn't save him.
"Charlie feels terrible because he had been playing with him but came home for his tea. He thinks if he'd stayed he may have been able to save him but perhaps he would have got in trouble himself.
"Kids always jump in the river here but it's not dredged and there are no life rings.
"We're all cut up about it, he was such lovely lad."
