Washington: A high-ranking US Navy captain has been sentenced to nearly four years in jail for passing classified information to a Malaysian defence contractor. Daniel Dusek provided the information in exchange for luxury hotel stays and the services of prostitutes, BBC reported. Desek was also ordered to pay a $70,000 fine and $30,000 in restitution to the navy. He is the highest-ranking officer to be charged in one of the US military's worst bribery scandals. Sentencing Dusek in San Diego, California to 46 months in prison, Judge Janis Sammartino said: "It is truly unimaginable to the court that someone in your position with the US Navy would sell out based on what was provided to you -- hotel rooms, entertainment and the services of prostitutes." Dusek, 49, who plead guilty in January 2015 to conspiracy to commit bribery, told the court he would never forgive himself for his actions.
