A partner at Baker & McKenzie has been indicted on charges that he participated in a stock fraud scheme that netted two overseas short-sellers $55 million.

According to an indictment unsealed Friday by federal prosecutors in the Eastern District of New York, Martin E. Weisberg, a mergers and acquisitions partner in Baker & McKenzie’s New York office, helped Israeli investors Zev Saltsman and Menachem Eitan gain access to hundreds of millions of discounted but restricted shares in two companies he represented.
