Mumbai police claim that Yahoo software engineer Mohammed Mansoor Asgar Peerbhoy, known to friends as "Mannu," used his English skills to finalize and send emails immediately before and after bomb blasts in three Indian cities that killed six people last week. The 31-year old Peerbhoy, who lives in the western Indian city of Pune, was one of eleven suspects arrested Monday. Peerbhoy was no call center flunkie — news reports in India make a point of quoting his salary and noting that he had traveled to the U.S. several times. One more twist: Police credit Muslim tipsters for the information that led to the arrests.
