Authorities searching for a missing 5-year-old New Jersey boy apparently abducted by his grandfather say the child may be in New York City.

State police are looking into “several locations” in Brooklyn where David Lundy may have been taken.

The child was last seen Friday evening near his West Windsor home. He suffers from a chronic illness, and it’s not known if he has his medication.

David, who is black, is 3 feet, 4 inches tall and weighs about 55 lbs. He was last seen wearing a white and green shirt and blue cargo shorts.

He’s believed to be with his grandfather, 50-year-old Morris “Tommy” Lundy of New York. Lundy, who is black, is 5 feet, 10 inches tall and weighs 180 pounds. Police believe he recently shaved his head.
