Federal officials in Manhattan charged Trent Martin, a citizen of Australia and a former research analyst at an international financial services firm, for his alleged involvement in an insider trading scheme.

Martin was charged with insider trading with Thomas C. Conradt and David J. Weishaus, two stock brokers who were arrested for the same offenses on November 29, 2012.

Federal officials alleged that Conradt and Weishaus and their co-conspirators traded on the basis of material, non-public information concerning IBM’s acquisition of a software company, SPSS, Inc., in 2009, earning in the aggregate more than $1 million in profits.

Martin was arrested on December 22, 2012 in Hong Kong pursuant to a request from the United States.

Following their earlier arrests in the United States, Conradt and Weishaus pled not guilty on December 7, 2012.
