HONG KONG: Hong Kong newspaper Apple Daily increased its Friday (Jun 18) press run after 500 police officers raided its newsroom on Thursday and seized reporting materials as part of a probe into whether articles threatened China's national security. 

Police arrested five executives, including editor-in-chief Ryan Law, at dawn on Thursday and froze HK$18 million (US$2.32 million) of assets owned by three companies linked to the paper before cordoning off the building.
