Pirate Capt Kidd's treasure 'found' in Madagascar Archaeologists in Madagascar say they have found what is thought to be the treasure of notorious Scottish pirate William Kidd. Soldiers have been guarding the 50kg silver bar at Sainte Marie island after divers brought it to shore from a shipwreck. Madagascar's president and UK and US diplomats received the suspected treasure at a ceremony on the island. Capt Kidd was executed in 1701 for piracy after returning from a voyage to the Indian Ocean. The BBC's Martin Vogl tweets from the ceremony that underwater explorer Barry Clifford believes the 17th Century silver bar is from the wreckage of the pirate's ship. BBC
