Quazi Mohammad Rezwanul Ahsan Nafis, who entered the United States in January on a student visa, was arrested after allegedly attempting to detonate what he thought was a 450-kilogram bomb outside the Federal Reserve Bank building. Authorities said the 21-year-old man had told an undercover federal source early this year that he had come to the United States to, quote, "wage jihad". In recorded meetings with an undercover FBI agent that Nafis thought was an al-Qaede contact, Nafis allegedly proposed an attack on New York's financial district. According to the federal criminal complaint, Nafis said he wanted to shake the whole country and possibly disrupt the U.S. presidential election.
