The FBI have charged a 21-year-old Bangladeshi national, Quazi Mohammad Rezwanul Ahsan Nafis, with attempting to use a weapon of mass destruction and attempting to provide material support to Al-Qaeda after an attempted attack on the Federal Reserve bank in New York.
The FBI claims that Nafis became a person of interest some months ago and was contacted by an undercover agent around three months ago after posting about Jihad online.
The details released by the FBI say that he travelled to the US in January to conduct the attack and believed that the 1,000 pound bomb he made was viable.
Despite allowing the planned attack to progress to this stage, the FBI has insisted that the public were never at risk:
The New York Post reported that the suspect parked a van filled with what he thought were explosives outside of the Liberty Street building, before trying to set the bomb off using a mobile phones.
Federal prosecutors have told the AP news agency that the man accused of trying to blow up the New York Federal Reserve had recorded a video statement.
It is alleged Quazi Mohammad Rezwanul Ahsan Nafis, 21, said: "We will not stop until we attain victory or martyrdom."
