Hundreds of children aged from four to 14, some of them armed with knives and sharpened sticks, were patrolling inside the historic graveyard.

They were, they told the bemused constable, hunting a 7ft tall vampire with iron teeth who had already kidnapped and eaten two local boys.

The blame was quickly laid at the door of American comic books with chilling titles such as Tales From The Crypt and The Vault of Horror, whose graphic images of terrifying monsters were becoming increasingly popular among Scottish youngsters.

The Gorbals Vampire will be broadcast on BBC Radio 4 at 2300 GMT on Tuesday 30 March, and will be available on BBC iPlayer(external link)
