SCHENECTADY — Officers grabbed a man perched in a tree off Interstate 890 and hauled him down about 4 a.m. Wednesday, after getting close to him in a fire engine bucket and offering him a blanket.

The man had been in the tree an estimated 11 hours, threatening to injure himself with a pair of knives and negotiating intermittently with authorities on the ground, police said.

The 29-year-old man, whose identity was withheld, got within reach of rescue workers as he tried to accept the offered blanket. He was pulled into the bucket and to safety.

He was unarmed at that point, after a previous attempt by officers to grab him at about 1 a.m. ended up getting his jacket and both knives, police department spokesman Lt. Brian Kilcullen said.

After shedding the jacket, the man also shed his shirt, leaving him open to the frigid overnight air.

“As he reached for the blanket, officers in the bucket were able to reach behind him and grab his pants,” Kilcullen said. No injuries were reported.

Police said the man never threatened anyone but himself. He was not charged in connection with the incident, though he was expected to face a warrant out for his arrest for failure to pay a fine on a marijuana conviction.

But police do not believe the warrant was the sole reason why he acted the way he did, Kilcullen said. “Obviously, he had some issues that brought him to the top of the tree.”

The man was taken unhurt to Ellis Hospital for evaluation. He had been up the tree since Tuesday afternoon, moving about the tree, occasionally poking his head from the branches.

He shinnied up just after 5 p.m. Tuesday after officers responded to reports from motorists. They had noticed a man urinating on the side of the road and dodging in and out of traffic. The man ran toward the woods when an officer arrived.

Once in the tree, the man displayed a pair of butcher knives and threatened to harm himself, police said.

Police and firefighters attempted to negotiate with the man from the ground but eventually resorted to raising a bucket from a city ladder truck.

Kilcullen credited the ordeal’s end to officers who worked to gain the man’s trust and keep him calm. Officers Marlon Ivery and Dwayne Johnson “really developed a rapport with him.”

At one point in the evening, the man asked for a turkey sandwich, which officers gave him.

Ivery was one of the three rescuers who ultimately grabbed the man. Fire Capt. David Orr and an off-duty FBI agent also helped make the grab, Kilcullen said. The agent, whose name Kilcullen did not have, was in the area when the ordeal began and offered to help.

Johnson, fire Capt. Greg Braungart and the agent made the first attempt and succeeded in getting the jacket and knives.

The incident shut down one lane westbound of I-890 as officials waited the man out. The shutdown would have been more extensive had the man had firearms, Kilcullen said.

Rotterdam and Scotia agencies assisted.
