The Baker & McKenzie partner indicted Friday on stock fraud charges in the Eastern District of New York was previously tried and acquitted on similar charges in a 1991 case brought by federal prosecutors in Texas.

Martin E. Weisberg, 57, a corporate partner in Chicago-based Baker & McKenzie’s New York office, and five other men were charged Friday with participating in an illegal short-selling scheme that netted two Israeli investors $55 million. The counts in the indictment include securities fraud, conspiracy and money laundering, and the defendants could face decades in prison and millions of dollars in fines if convicted.
