Prospective Manchester City owner Thaksin Shinawatra has been ordered back to Thailand.
The former Thai Prime Minister and his wife have been charged with concealing assets.
Police have ordered the exiled leader to return to Thailand and appear before them by June 29 or face arrest. He is currently living in London.
Department of Special Investigations Director-General Sunai Manomaiudom said police had strong evidence that Thaksin and his wife secretly held stock through nominee companies in SC Assets Corp. PLC, a Shinawatra family holding company.
Serving Thai Cabinet ministers are not generally allowed by law to hold shares in publicly listed companies. They are also required to reveal their assets, including stockholdings.
The police are charging Thaksin with violations on both counts when he was Prime Minister.
