Swiss officials said Monday that they had refused a request by the U.S. to extradite Roman Polanski to face sentencing for sex crime charges. In 1978, the Oscar-winning film director fled to Europe hours before he was to be sentenced after pleading guilty to having unlawful sex with a minor. California and U.S. authorities have been pursuing him for the last 30 years.

The guilty plea was a result of a deal and Polanski served 42 days in a Los Angeles jail under psychiatric evaluation before his formal sentencing. Swiss authorities say that they were not provided with the documents that would have helped them determine whether the time already served by Polanski was enough to fulfill his sentence.
