A teenager was airlifted to hospital yesterday after his leg was caught in a motorboat propeller on a lake in Fairlop Waters.

The boy was understood to be on an activity trip building rafts with a Chingford school when the accident happened around 3.30pm.

Firefighters from Dagenham were the first on the scene as they were in the park, in Forest Road, Barkingside, on a training exercise.

Watch manager Lee Ware said: “When we got over there the lad was in shallow water.

“We went in to release his leg. It was trapped by his shoelaces and we cut the laces and brought him to the shore.

“The injury was serious but not life-threatening.”

A London Ambulance Service spokesman said an ambulance crew, motorbike responder and the air ambulance attended.

The boy was airlifted to the Major Trauma Unit of the Royal London Hospital in Whitechapel.

The spokesman said the teenager was “conscious and breathing” at the time.
