André Lussi, the president of Clearstream who was suspended last week, hired his stepdaughter to help run the human resources department at the settlement firm.

Caroline Wiget, the daughter of Lussi's wife, has been working at Clearstream as a senior HR manager. Her boss, Robert Massol, head of HR at Clearstream, was suspended last week along with Lussi and Carlos Salvatori, a senior director at the firm, in the wake of the investigation into alleged money-laundering by the Luxembourg authorities.
