A former Mizuho investment banker and two associates have been charged with insider dealing by the Financial Services Authority (FSA).
Thomas Ammann, who was fired by the Japanese bank when he was arrested last November, faces three counts of insider dealing, plus a further count of money laundering and two more alleging encouragement of insider dealing.
The charges relate to trades in shares of Dutch electronic equipment maker Océ between February and November 2009, the FSA said yesterday. Mr Ammann worked for Mizuho when the bank was advising Japanese giant Canon about its $1.3bn takeover of Océ in 2010.
Two others are also being charged alongside Mr Ammann. Christina Weckwerth, who lives in Germany but holds a British passport, faces two counts of insider dealing and one of money laundering. And Jessica Mang faces one count of insider dealing.
Mizuho was quick to distance itself from the three accused yesterday, emphasising that only Mr Ammann was connected with the bank.
"The transactions to which the charges relate were... not done through or processed by Mizuho International," a spokesman for the bank said ;ast night.
"The FSA has not expressed any concern about Mizuho International or its systems and controls."
The FSA is already prosecuting another 13 insider-dealing cases.Reuse content
