A mother has started her immobilised car by holding her baby son over the steering wheel.
Amanda Webster, from Oxfordshire, had been left stranded in west London after her one-year-old son Oscar ate the radio transponder of her car key.
The tiny part, which was only the size of an aspirin, managed to make contact with the car's immobiliser - even though it was passing through the child's stomach at the time.
Mrs Webster called in the RAC when the car failed to start. Patrolman Keith Scott has told BBC News Online: "His mum remembered that Oscar had been sucking at the keys, and when we looked at them, the cover over the transmitter was off and the transmitter wasn't there. It dawned on us that Oscar had probably swallowed it."
"His mum sat in the driver's seat, and put him on her lap with his tummy pressed up against the wheel. We were amazed when she turned the key and the car burst into life."
