BEIRUT, May 21 (AFP) - Lebanese police detained another senior official of billionaire former prime minister Rafic Hariri Friday as prosecutors widened their inquiries into alleged corruption under his former government. Kahtane Hamade, former director of the National Fund for Medicines, an autonomous executive agency, was remanded in custody after questioning by the advocate general for financial affairs, Maher Hammmoud, judicial sources said. Hamade was being held in connection with allegations that he embezzled public money during his stewardship of the fund, the sources said. President Emile Lahoud launched a major crackdown on corruption soon after taking office last year and prosecutors have launched a string of investigations since early March into alleged corruption by former high officials. The government ordered a judicial inquiry at the beginning of April into a 600-million-dollar corruption scandal allegedly involving Hariri. Earlier this month the prosecutor's office issued a subpoena for a former governor of Mount Lebanon province, Suhail Yamut, and summoned three former ministers -- ex-finance minister Fuad Saniora and ex-municipal affairs ministers Bassem al-Sabeh and Agop Demirjian -- for questioning. Police have already detained the former director-general of the antiquities department, Camille Asmar, and his son, and charged five other members of his department with embezzlement.
