The body of a 12-year-old boy has been pulled from a river on the outskirts of Cambridge after he was seen entering the water on Tuesday night.
Cambridgeshire Police and other emergency services launched a search after reports that the boy did not resurface after going into the River Cam at Lammas Land, the Fen Causeway, at about 6pm.
Inspector Kate Scott said: "Emergency services recovered the body of the boy, who was deceased, at about 3am."
According to the Cambridge News, the boy's family watched as officers, paramedics, fire crews and a police helicopter searched the water. Rescue teams were seen dredging the river.
One witness told the paper: "The police helicopter was up and the firefighters were everywhere. They were going up and down the river looking for a child.
"We heard that four boys had gone into the river but only three came out and one didn't."
A spokesman for East of England Ambulance Service said: "We received the call at 6.11pm to an incident involving a 12-year-old boy in water.
"We sent three ambulances, a rapid response vehicle and a land crew from East Anglia Air Ambulance."
