ATHENS, June 23 (RIA Novosti) - A prominent Greek industrialist was released by his kidnappers on Monday after 13 days in captivity when his family paid a 12 million euro ($18.6 million) ransom, Greek television reported.

Giorgos Mylonas, the CEO of Greece's Alumil Aluminium company, was kidnapped by unidentified gunmen shortly before midnight on June 9 in Thessaloniki, as he was driving home with his wife.

The kidnappers later released his wife, but the businessman was taken hostage and a 30 million euro ($46.7 million) ransom was demanded for his release.

Mylonas, 49, arrived home in a stolen BMW provided by the gang after his family left the money at an undisclosed location on Saturday.

Alumil SA is a Greek aluminum conglomerate with subsidiaries in Europe, Africa and the Middle East. Shortly after Mylonas' kidnapping, trading in the company's shares was suspended on the Athens stock exchange.
