Surveillance footage shows the boy sitting on a curb, with his back obliviously turned to the man striding towards him from behind.

Without warning, he stoops down and swings a brutal blow at the child's head, knocking him unconscious, before calmly walking away.

The victim suffered fractures to his face, bleeding and bruising. He was taken to Coney Island hospital and was in stable condition after treatment, ABC7 reported.

He told police his assailant didn't say a word to him.

Neighbors told the broadcaster the victim is a good kid: "That's atrocious, disgusting, who would do that to a child?" one asked.

Police have offered a $2,500 reward for information, describing the suspect as a white male, aged between 20 and 30.
