New York City's new FBI director believes terrorist groups could have a presence in the city.
Pasquale D'Amuro was appointed director of the New York City FBI last month.
He says the agency is investigating certain groups in the city.
He told WNBC with any cause in the world, "somewhere in New York there is a group of individuals that may sympathize with that particular cause."
He also says al-Qaida sleeper cells have popped up in rural America since the September eleventh attacks. He says the FBI's top priority is to identify those cells and keep them from striking again.
Already, he says, law enforcement officials have arrested "significant numbers" of people with ties to al-Qaida.
