It took almost a dozen NYPD officers about three hours to talk the 39-year-old man from leaping off the Williamsburg Bridge on Saturday morning.
Police responded after getting 911 calls about a person on the Brooklyn side of the bridge.
Two detectives wearing rescue gear climbed up while talking to the man, who police say kept leaning over the side. He indicated he would jump from a height of about eight stories to Berry Street below - two blocks from the East River.
Police gradually brought him down. He's at Bellevue Hospital under observation.
Authorities did not release his name.
