A prank almost proved fatal when a 28-year-old man got a whole live dover sole stuck in his throat.

The man had just caught the 14cm fish and had put it over his mouth as a joke but it wriggled free and jumped down his windpipe – causing a complete blockage.

Paramedics were called and when they arrived at Boscombe pier in Dorset on the night of 5 October they found that the man, who has not been identified, had collapsed and stopped breathing.
