French police said on Wednesday they had seized a significant portion of an ancient Roman treasure that was discovered more than two decades ago by Corsican divers who became rich by secretly selling it off.
The seizure is the latest chapter in the exploits of a then young Corsican and two friends who spotted gold in shallow waters 25 years ago while diving for sea urchins off the coast of the Mediterranean island.
The three friends enriched themselves by selling the coins and medallions on the black market and later claimed that they had inherited them when the source of their newfound wealth was discovered by the local authorities.
Police did not say on Wednesday from whom they had recovered the latest portion of the treasure, which likely came from an ancient shipwreck. Specialists consider the find to be one of the most important related to ancient coins, dating from the 3rd century AD.
"This submerged treasure, identified as a maritime cultural asset, belongs to the state," France's national police said in a statement, after a long investigation into national and international black markets for antiquities.
One of the original three Corsican friends, Felix Biancamaria, told French daily Liberation in 2005 how the discovery of what he quickly suspected were Roman coins brought him and his fellow divers untold wealth and thrills until the party soured when local police caught wind of their exploits.
