Hong Kong, Sep 18 (DPA) A former Morgan Stanley executive was jailed Friday for seven years for what a judge called his 'sheer greed' in Hong Kong's biggest insider trading case.

Du Jun, 40, a former managing director of Morgan Stanley Asia, bought $11.22 million in shares in Citic Resources after getting inside information about an acquisition.

The deal in 2007 earned him a profit of nearly $3 million after he had borrowed millions of US dollars to allow him and his wife to snap up shares in the company.

The banker, who began working with Morgan Stanley in Hong Kong in 2001, was convicted last week of nine counts of insider trading and one count of advising his wife to deal in Citic Resources shares.

Sentencing him to jail for the maximum possible jail term of seven years and fining him $3 million, District Court judge Andrew Chan said Friday that Du had been 'driven by sheer greed'.
