A terrifying attack by a killer shark shattered the peace at a quiet North London fishmonger after one bloodthirsty beast was let loose amid the catch of the day.

Razor-sharp teeth... glassy dead eyes... and an immense cavernous mouth...

But fortunately for the shoppers and staff at the fishmongers, this wasn't a real shark – but a stunt dreamed up by special effects producers at Syfy to celebrate the release of Sharknado 2: The Second One.
