A Brooklyn teenager is fighting for his life after falling off an eight-story building in East New York Tuesday morning, police say.

Police found the 17-year-old on the ground with multiple injuries, including two broken wrists, a broken leg, bruises all over his body and internal injuries. Authorities say the teenager is in serious condition at Brookdale Hospital.

Neighbors claim the teen victim was thrown off the rooftop of Pink Houses at 1306 Loring Ave. According to unconfirmed reports, the teenager?s hands had been duct taped.

"If he was duct taped, it's common sense someone threw him off the building because he couldn't throw himself," says neighbor Tiz Glenn.

Police officers scoured the rooftop of the housing complex for clues. They shut down the elevators in the building while the investigation continues.
