A Canadian man climbed up a red sculpture in Zuccotti Park early on Saturday and perched there for several hours before the police brought him down, the authorities said.
The man, Dylan Spoelstra, 24, of Toronto, was taken to Bellevue Hospital Center after the episode, the authorities said.
“He was not arrested, he did not get a summons, he’ll just be evaluated psychologically,” according to a law enforcement official, who said the incident was still being investigated.
Mr. Spoelstra, dressed rather scantily for an autumn morning in a T-shirt and trousers, ascended the distinctive sculpture, ”Joie de Vivre,” by Mark di Suvero, about 6 a.m. and perched on a platform about 30 feet high.
He “would not come down unless he spoke to the mayor,” the official said. “He was also talking about financial issues.”
It was not immediately clear if he was a member of the protesters at Zuccotti Park.
Officers from the Police Department’s hostage negotiation unit, who are adept at speaking with emotionally disturbed people, arrived, as did officers from the elite Emergency Service Unit, who are also trained in sensitive tactical situations. Some officers inflated a large airbag and placed it around the base of the sculpture.
At one point, an officer climbed into a cherry picker and was raised up to Mr. Spoelstra’s height for some “face-to-face dialogue,” the official said.
Mr. Spoelstra was also given a telephone that connected him with police negotiators. As the minutes ticked by, he tried to stay warm.
“He was requesting a jacket,” the official said. “He’s a smoker, and he kept asking for a cigarette.”
Mr. Spoelstra was given a cigarette — just one. But he did not get a jacket. He also never got to speak to the mayor.
Eventually, about 9:15 a.m., he climbed into the cherry picker and came down.
Mr. Spoelstra told police officers he had received a summons for public urination a few hours before making his climb. He told officers he had “urinated against a wall.”
But the police said they could not confirm that he had been issued a summons.
