NEW YORK (AP) — New York City Police Commissioner Raymond Kelly says the 21-year-old arrested on charges that he plotted to blow up the Federal Reserve building in Manhattan came to the U.S. on a student visa.

Quazi Nafis was arrested early Wednesday on charges he tried to detonate a fake bomb outside the building.

Kelly says the Bangladeshi man came under the guise of going to school in Missouri but was really plotting an attack.

Authorities tracked him using Facebook and other social media, but the account was taken down Wednesday.

Kelly says the city remains at the top of the terrorist target list.
