Barot, alleged leader of a terrorist cell, was arrested in London for plotting to attack the New York Stock Exchange and Citigroup Center in Manhattan, the International Monetary Fund and World Bank in Washington, and Prudential Financial Inc.'s headquarters in Newark, N.J. A July 2004 police raid on Barot's house in Pakistan unearthed several files on a laptop computer, including instructions for a plot in Britain known as the "Gas Limos Project," as well as company histories and organizational charts for the US targets. Barot, a Briton and former Hindu who converted to Islam, pleaded guilty to conspiracy to commit mass murder. He was sentenced to 40 years; in May 2007 his sentence was reduced to 30 years.
The two were charged with plotting to place explosive devices at the Herald Square subway station near Madison Square Garden in New York before the Republican National Convention. Government evidence included hours of secretly recorded conversations between Siraj and Osama Eldawoody, an Egyptian nuclear engineer who became a paid informant for the New York Police Department's intelligence division, and who testified against Elshafay and Siraj. Siraj, a Pakistan national, was convicted and sentenced to 30 years in prison. Elshafay, a US citizen, pleaded guilty and received a reduced sentence for testifying against Siraj.
