Oil tycoon John Deuss has been given a six-month suspended jail sentence and a fine of 327,000 euros ($409,000) after being convicted by a Dutch court of banking without a licence and not reporting unusual transactions.The 69-year-old went on trial in Arnhem more than five years after he was arrested in Bermuda.He was accused of membership of a criminal organisation, not reporting unusual transactions and illegal banking involving his First Curacao International Bank, (FCIB) according to reports from the Netherlands.According to the De Telegraaf newspaper in Amsterdam, the judge found the allegations that Deuss was a member of a criminal organisation to be unproven.He stood trial with his sister Tineke, 66, of Berg en Dal in Holland, and they both denied the charges.His sister was convicted of the same charges and received the same fine. Both must serve two years of probation. The FCIB must pay a 1.2 million euro ($1.5 million) fine.The Dutch businessman was once one of the world's best-known oil dealers.He has a home in Bermuda and was arrested here in October 2006 before being voluntarily extradited to his homeland.He denied any wrongdoing and later returned to the Island while investigators continued to probe allegations about FCIB.* Harry van Gelder is a reporter on De Telegraaf newspaper in Amsterdam.
