Divers in Madagascar may have found part of Captain Kidd's legendary treasure.

A 50kg silver bar, engraved with the initial TS, was found in the waters around the island of Sainte Marie and is currently undergoing analysis.

Captain Kidd was a notorious British privateer

It's thought to originate from the wreck of the Adventure Galley, one of Kidd's ships - which was sunk in 1698.

Kidd was a privateer, employed by the British crown to hunt the ships of rival nations.

However, his brutal conduct and capture of ships of dubious nationhood (he took an Armenian ship captained by an Englishman) led to him being hung as a pirate on his return to England.

Explorer Barry Clifford, who found the treasure, told the BBC: "Captain's Kidd's treasure is the stuff of legends. People have been looking for it for 300 years.

"To literally have it hit me on the head - I thought what the heck just happened to me. I really didn't expect this.

"There's more down there. I know the whole bottom of the cavity where I found the silver bar is filled with metal. It's too murky down there to see what metal, but my metal detector tells me there is metal on all sides."
