BEIJING, Jan 31 (Reuters) - Three units of HNA, once China’s most acquisitive conglomerate, said nearly $10 billion had been embezzled by shareholders, in disclosures to stock exchanges that come amid a government-led probe into the deeply indebted group. A total of 61.5 billion yuan ($9.57 billion) had been embezzled by shareholders and other related parties, Shanghai-listed Hainan Airlines Holding Co, HNA Infrastructure Investment Group Co and Shenzhen-listed CCOOP Group Co said late on Friday.
