A signed first edition of the novel "One Hundred Years of Solitude" by the late Colombian author Gabriel Garcia Marquez has been stolen. It was being exhibited in a locked cabinet at the International Book Fair in the Colombian capital, Bogota.

The fair, which closes on Monday, is dedicated to Garcia Marquez, who died last year at the age of 87. The book is estimated to be worth $60,000 (£40,000) but its owner says for him its value is immeasurable.
