Chinese state media say a policeman and a journalist have been detained over the leaking of documents in the case of a spiritual guide linked to a disgraced official and others.
The Xinhua News Agency says the policeman, identified only by his surname, Zhong, and a journalist surnamed Liu are under investigation for bribe taking.
It says the ex-wife and a former lover of spiritual master Wang Lin are suspected of colluding with them to leak documents that could help Wang's case.
Wang claims to have supernatural powers as a master of qigong, but was arrested in August and charged with illegal detention in the kidnapping and murder of a former acolyte.
Wang once had the trust of former Chinese railways minister Liu Zhijun, who fell in a corruption scandal.
