DHAKA, Bangladesh (AP) — The Bangladeshi man accused of trying to bomb the Federal Reserve building in New York City was a banker’s son from a middle class neighborhood whose family says it was stunned by his arrest.

The FBI arrested Quazi Mohammad Rezwanul Ahsan Nafis after he tried to detonate a fake 1,000-pound (454-kilogram) car bomb, according to a criminal complaint.

His family said Thursday that Nafis was a gentle man incapable of such actions.

"My son can’t do it," said his father, Quazi Ahsanullah.

He called on the Bangladesh government to intervene to get his son back to his home country.
