A teenage boy who fell down a manhole in Whittlesey Road, Stanground has been released after being trapped for more than half an hour.
It is thought the boy became trapped at about 4pm. Witness reports said his head was below pavement level when he became trapped.
Fire and rescue crews worked with police and ambulance staff to release the boy, and he had been freed by 4.25pm.
Nadine Jones, who called 999 after seeing the boy, said: “A child fell into the drain and became stuck.
“The drain cover was a loose, plastic temporary one, rather than a metal one, as works had been taking place.
“You could not see the top of his head. I think the drain was about eight foot deep.”
An East of England Ambulance service spokesman said: “An ambulance and a rapid response vehicle attended and treated the boy, whose leg was trapped in a drain. He was discharged from scene and was not taken to hospital.”
A Cambridgeshire police spokesman said: “We were called at 3.57pm to an incident on Whittlesey Road as a child had fallen down a manhole.
“Two fire crews and an ambulance were also on scene.
“It is reported the drain cover was rubber, and had been kicked out of position.”
