Suffolk County Police say a bomb-making teenager accidentally set off one of his explosives and unconfirmed reports say he may have amputated one of his hands Monday evening.

Officers arrived at 29 Pell Avenue in North Babylon, Long Island just before 7:30 p.m. when the youth's parents called 911 to report their 17-year-old son, Vincent Pizzonia, was injured.

Police say the teenager, a student, was in the process of creating an improvised explosive device in his basement at the time of the unexpected detonation.

The young man's parents transported him to Good Samaritan Hospital in West Islip in unknown condition. Reports say the teen may have blasted one of his hands off.

Neighbors told PIX News Pizzonia's his father is a retired cop. They described the youth as a "normal" boy, who has never been in any kind of trouble.

PIX cameras captured images of what appeared to be a bloodstained T-shirt, which may have belonged to the teen, on the driveway of the Long Island home.

An arson squad was called when responding officers discovered more home-made explosive devices and bomb-making equipment on the premises.

Suffolk County Police Department's Arson Squad is continuing their investigation with the assistance of the Bureau of Alcohol, Tobacco, Firearms and Explosives.
