NEW YORK (CBSNewYork) -- The search for Leibby Kletzky continued Tuesday night more than a day after the 9-year-old boy from Borough Park went missing. Two new surveillance videos are being seen as possible leads in the disappearance.
One video showed the young boy leaving his day camp, located at 12th Avenue and 44th Street, and walking past his home on 15th Avenue.
A second video, which was released late Tuesday night, showed the boy walking behind another man, according to police. Investigators believe Kletzky may have gotten into the man's gold-colored sedan.

Kletzky may have stopped to talk to a man and followed him in the opposite direction. Tuesday, the boy's father went with detectives to watch the video and confirm it was his son, CBS 2's Sean Hennessey reported.
"We look at the possibility of foul play right from the beginning," NYPD Chief Joe Esposito said.
CBS 2 has also confirmed that Congressman Jerrold Nadler specifically reached out to the FBI's New York field office to request federal resources to assist in finding Kletzky.
The FBI has been deployed to the scene and is currently providing the NYPD with assistance, according to Nadler's office.
Kletzky was supposed to meet his mother at 5 p.m. Monday at the corner of 13th Avenue and 50th Street after leaving day camp in Brooklyn, but he never showed up.
Since Monday night, volunteers organized by the Flatbush Shomrim -- the Jewish community patrols -- have fanned out from Borough Park looking for the boy.

Police also had a K-9 dog at the boy's day camp, hoping to pick up the scent. But after heading in the direction the boy walked, the trail went cold. The community flooded the area with announcements, posters and volunteers in a desperate search.
"We're concerned. We feel like its one of ours," said Esther Mandel of Borough Park.
Kletzky had begged his parents to let him walk home, CBS 2's Pablo Guzman reported. They had given him a note, saying he would not be taking the bus. His parents are still waiting for their son's safe return.
"I wouldn't wish what they're going through on my worst enemy -- plain and simple," Assemblyman Dov Hikind said.
It's unclear if Leibby's disappearance is suspicious, but residents said they're not taking any chances.
"Everywhere, up and down the neighborhood, every single block, every park, and so have hundreds of others," one resident told CBS 2's Kristin Thorne.
At the day camp, people said the children were susceptible to suggestions from strangers.
"He respects everyone...if you would tell him, you yourself were to tell him, 'I would like you to sit here until I come back', he would sit down until you come back," said Jacob Baskal of the Borough Park Shomrim.

"We have 2,000 people searching for the kid. We went through every backyard, every front yard, every possibility," search coordinator Shi Lichtenstein told WCBS 880's Mike Xirinachs.
Steve Sandberg of 1010 WINS reported that the search included people on horseback as well as in helicopters.
Hikind also spoke with the boy's family earlier and said, "They're scared. They're afraid. I tried to give them strength and told them to have faith in God."
The boy is described as 4-foot-4, with dark hair, wearing black glasses, a striped shirt, and was carrying a knapsack.
A $100,000 reward is being offered for the boy's safe return. Anyone with any information is encouraged to call either the police at 718-851-5641 or the Shomrim at 718-871-6666.
