Hong Kong (CNN) -- Two billionaire brothers who control Asia's biggest property development company have been charged with corruption, anti-bribery officials in Hong Kong said Friday. Sun Hung Kai Properties (SHKP) co-chairmen Thomas and Raymond Kwok were among five people charged with a total of eight offenses, including conspiracy to offer advantages to a public servant and misconduct in public office, the Independent Commission Against Corruption (ICAC) said in a statement. Hong Kong's former chief secretary Rafael Hui, banker Francis Kwan and Thomas Chan -- responsible for land acquisitions for SHKP -- were the other men charged after one of the biggest anti-graft probes in the banking hub's history.
