BREAKING: Quazi Mohammad Rezwanul Ahsan Nafis arrested after allegedly trying to blow up Fed building in NYC

(Fox News) DEVELOPING: Federal authorities arrested a Bangladeshi national Wednesday morning for allegedly plotting to blow up a Federal Reserve building in New York City's lower Manhattan, mere blocks away from the site of the terrorist attack of Sept. 11, 2001.

The 21-year-old suspect, Quazi Mohammad Rezwanul Ahsan Nafis, attempted to detonate what he thought was a 1,000-pound bomb in front of the Fed building on Liberty Street, but the device was a fake supplied to him by undercover FBI agents who had been tracking his activity, the FBI's Joint Terrorism Task Force said Wednesday afternoon.

The supposed explosives posed no threat to the public, the FBI said.

A criminal complaint accuses Nafis of having overseas connections to Al Qaeda and travelling to the U.S. in January to recruit individuals to form a terrorist cell and conduct an attack on American soil. But one of Nafis' potential recruits was an FBI source, who alerted authorities, the FBI said.
