The mainland's anti-graft agency has confirmed that top intelligence official Ma Jian is under investigation as the country's anti-corruption campaign widens to cover its security and intelligence apparatus.
"Vice-minister and member of the party committee of the State Security Ministry Ma Jian has been put under investigation for suspected serious violation of discipline and laws," the Central Commission for Discipline Inspection (CCDI) said in a one-sentence statement posted on its website yesterday.
The South China Morning Post reported Ma's detention on corruption charges on Monday.
Ma is closely linked to Ling Jihua , the ex-aide of former president Hu Jintao . Ling was detained last month, also on corruption charges.
Hours after its statement about the inquiry into Ma, the CCDI announced the detention of Ling's former aide, Huo Ke . Huo was a division head in the General Office of the Communist Party's Central Committee, before being transferred to the China National Tourism Administration.
Ma is the highest-ranking national security official to be investigated since the downfall of Zhou Yongkang , the former security tsar.
