NEW HAVEN, Conn. (AP) – A New York man has pleaded not guilty to charges that he had explosive materials in his car.

Yung Tang was charged with four counts of possession of a firearm, specifically two improvised explosive devices and two silencers, and one count of transporting explosive materials without a license.

Tang, a Chinese citizen who lives in Greenwood Lake, N.Y., already faced charges in a 2002 pipe bomb attack in New York that blew off part of a man’s leg.

Last month, police say the 38-year-old was found asleep in a car in Wallingford with homemade explosives and other items including a disguise.

Tang has been detained since his arrest.
