A senior volleyball official with China's General Administration of Sport (GAS) is under investigation for graft, said China's top discipline inspection agency Tuesday.

Pan Zhichen, director of the GAS volleyball administrative center, is being investigated for "serious violations of discipline and law," said a statement on the website of the Central Commission for Discipline Inspection (CCDI) of the Communist Party of China, quoting the GAS discipline inspection division.

China's anti-corruption campaign has swept various sectors and fields, including the country's sport administration.

In June, Xiao Tian, then GAS deputy director, was investigated by the CCDI for "serious breaches of discipline and law." He was dismissed in July.

The CCDI conducted an anti-corruption inspection on the GAS from July to September of 2014 and criticized the administration for bureaucracy, poor management and malpractice, including manipulating games.
