Carson Yeung Ka Sing (Chinese: 楊家誠; pinyin: Yáng Jiāchéng; Wade–Giles: Yang Chia-ch'eng; born 27 February 1960)[1] is a Hong Kong businessman who, until February 2014, was the president of English football club Birmingham City F.C., and chairman and an executive director of Birmingham International Holdings (previously Grandtop International Holdings), an investment, entertainment and sportswear firm registered in the Cayman Islands,[2] which owns that club.

[6] Yeung began his investment career making his first fortune in the Hong Kong Real Estate industry.

[10] On 12 August 2009, Birmingham City confirmed that Yeung's Grandtop International Holdings held 29.9% of the club's shares and had made a further offer.

[16] In addition, Beijing was stepping up measures to cool off the mainland property market, which affected his revenue streams.

A brief statement mentioned that Narcotics Bureau officers searched two locations – one on Hong Kong Island and the other in Kowloon – and seized documents.

Given permission to travel after his cash bail was doubled to HK$8 million the prosecution appealed on the grounds there was a risk of him not returning.

[20] Yeung's trial opened in May 2013 and lasted until March 2014, when he was found guilty on five counts of money laundering a total of HK$720 million and was sentenced to six years' imprisonment.

[5] The trial judge, Douglas Yau, commented that Yeung was "not a witness of truth",[21] and that his sentence included a necessary element of deterrence.
