With its razor- sharp teeth, the fish known as the giant snakehead terrorises the warm waters of south-east Asia. Which is why an angler was particularly startled to hook a 2ft specimen from a river in Lincolnshire. Andrew Alder caught the snakehead using a sprat for bait while fishing for pike in the River Witham near North Hykeham. He took photographs of his catch and handed them over to experts who confirmed it was the deadly predator.
