Hong Kong-based China Resources confirmed late Thursday that Song Lin, chairman of the State-owned enterprise, is under investigation for suspected serious violations of discipline and law.

The company said in a statement that it would cooperate fully with the anti-graft authority and work to ensure its businesses run normal. The person in charge of the company's public relations said no further information were available for the moment.

The Central Commission for Discipline Inspection (CCDI) of the Communist Party of China and the Mini stry of Supervision released the news on the official website on Thursday.

Song was earlier publicly tipped off, for the second time, by a journalist with the Xinhua-run Economic Information Daily on Tuesday.

Wang Wenzhi, the journalist, claimed that Song was suspected of embezzlement, dereliction of duty and keeping mistress.
