Ha But Yee admits paying HK$6.4m to Ma Sin Chi between Jan-2007 and May-2008, for information on derivative warrants issued by DB. Mr Ha and his family made a net profit of over HK$203m through trading of DB warrants. Ma remained a Responsible Officer of DB until 6-Jan-2012. The ICAC doesn't mention that this guilty plea follows a previous trial in which the defendants were found guilty but the convictions were quashed by the Court of Appeal due to misdirection of the jury by the Judge. By then, they had already served 2.5 years of a 7-year sentence.
