Holidaymaker claims to have shot footage of a large shark fin swimming up British river

A holidaymaker claims to have shot footage of a large SHARK fin - swimming up a British river. Stunned Gemma Walters said her children were playing in the water when she spotted the fin going against the tide. Initially she didn't know what it was, but one of her children soon said, 'it's a shark', and Gemma rushed to get her other kids out the water. She then captured the footage, which appears to show a sizeable fin, too big for a dolphin, swimming in the River Teign in Devon.
