Two workers withdrew assault charges filed against the son of Libyan leader Muammar Gaddafi in Switzerland, their attorney said Tuesday. "My clients have decided to withdraw the criminal complaint that they had entered," Francois Membrez said in a statement. "Their interests were safeguarded in so far as they were correctly compensated. They were recognized as victims and their suffering was acknowledged," the statement continued. Hannibal Gaddafi and his wife Aline were charged with ill-treatment of their two employees in Geneva in July after hotel staff told police about arguments in their suite.
