Guo is the chairman of the Fosun Group that owns Club Med chain of resorts and has shares at the entertainment company Cirque du Soleil.

He also holds various CEO positions in insurance companies and property holdings.

Reports said Guo's disappearance is just the latest in a series of mysterious disappearances of top level executives since August, as China stepped up its anti-corruption investigation into the financial industry.

Reports said these executives were either arrested and taken into custody for questioning, while the others have totally disappeared without any trace.

Some witnesses reportedly saw police taking Guo Guangchang away at a Shanghai airport after landing in Hong Kong.

The 48-year old billionaire has been unreachable since Thursday noon, but family members said he was in Shanghai. Calls to his mobile phone were redirected to his secretary.

Trading of shares in Fosun International and Fosun Pharmaceutical was halted as Guo's whereabouts remain unknown. Reports said five other listed companies under the Fosun Group also suspended trade.

On Sunday, China's largest brokerage firm, Citic Securities, said two of its top executives have gone missing since last week.

In August, a Shanghai court said Fosun International had questionable and inappropriate  ties with Wang Zongnan who was then the president of a state enterprise and who was sentenced to 18 years in prison for embezzlement and corruption.

Fosun denied the accusation and said no such ties existed between the two.

Guo ranks 11th on Forbes China Rich List, and 259th on the Forbes Billionaire List, with a net worth of nearly $7 billion, according to Forbes.
