Liu Yuejin, former commissioner for counter-terrorism at the Ministry of Public Security, has been expelled from the Party for seriously violating Party disciplines and laws, the country's top anti-graft watchdogs announced on Wednesday.

Liu, who was also a member of the 13th National Committee of the Chinese People's Political Consultative Conference, once held a position at the vice-ministerial level. His case and involved assets have been transferred to procuratorial organs for review and prosecution, according to a statement from the Central Commission for Discipline Inspection of the Communist Party of China and the National Supervisory Commission, the nation's top anti-corruption watchdogs.

Liu was disloyal to the Party and dishonest, and he resisted the investigation conducted by the Party organizations, the statement said. The watchdogs found that he violated regulations by frequenting private clubs and accepting banquet invitations there, and he failed to provide truthful explanations during their inquiries, it said.

He also accepted gifts, retained classified documents without authorization, and took advantage of his position to benefit others in enterprise operations and case handling, accepting substantial bribes in return, the watchdogs reported.

Liu, 65, began working in 1974 and joined the Party in 1977. He served in the anti-drug sector for many years and became head of the Office of the China National Narcotics Control Commission in May 2015.

He served as the commissioner for counter-terrorism at the ministry from December 2015 until June 2020.

In October 2011, Liu led a special task force to investigate the Mekong River massacre, in which 13 Chinese crew members aboard two cargo ships were killed by cohorts of drug lord Sai Naw Kham in the border area between Myanmar and Thailand.

Liu was placed under investigation in March this year.
