Families watched in horror as an endangered monkey was mauled to death by a pride of lions at one of the UK’s leading safari parks. An investigation has been launched after the Barbary macaque escaped from its own reserve and climbed into the lions’ den. Its screams could be heard across the Blair Drummond Safari Park as the big cats tore at its neck and limbs in full view of paying customers. One of the park’s keepers tried to shield the gravely injured monkey by parking his pick-up truck over its stricken body, but a lion snatched it from under the vehicle and ran off with it in its jaws.
