Seven-year-old Amelia Drewett and her grandfather Alan found the scales underneath a bridge in the area and the skin has been verified by experts.

The section of skin is 5.5 feet long and it is believed that the reptile could be several feet longer.

Amelia's grandmother has appealed for the snake's owner to come forward but its whereabouts remain a mystery.

She told the Oxford Mail newspaper: "I couldn't believe my eyes when they brought it home.

"They thought it was just plastic in the brambles under the bridge, but they took a closer look and it was this huge snakeskin.

"Nobody’s come up with any sort of reasonable explanation for how it got there."
