DOES anyone know what happened to Stanley Adams, who blew the whistle on Swiss pharmaceutical company Hoffman-LaRoche in the 1970s?

He is believed to still be living in Weymouth, now aged 90, and Patrick Roesing from Hamburg, Germany, is trying to track him down.

In 1973 Maltese-born Adams discovered documents which indicated that Hoffman-LaRoche was involved in price-fixing to artificially inflate the price of vitamins.

He told the EEC Commission that the company was breaking Common Market regulations forbidding firms from abusing their dominant position by market-sharing practices and price-fixing.

A year before reporting Hoffmann-La Roche, he had left the company and set up his own business in Italy.

While visiting Switzerland, he was arrested for breaching trade secrets and giving economic information to a foreign power.

While he was in prison, his wife committed suicide after being told he would serve 20 years. He jumped bail when he was released several months later and left Switzerland. He later discovered that the EEC had told Hoffmann-La Roche that he had been the source of the price-fixing report. The company was fined pounds 150,000 and Mr Adams received a 12-month suspended sentence in absentia in Switzerland.

Adams emerged from prison in 1998, having served five and a half years for the attempted murder of his second wife. He had hired a hitman, wanting to benefit from her life insurance. Adams was last known to be living in Weymouth in 2011.

Patrick said: "Does anybody know about his whereabouts and can help me find him? If yes, I would be very thankful."
