Runaway boy, 8, safe after a night riding subway

An 8-year-old boy who went missing from his family’s Gramercy Park Monday home went on a 15-hour adventure around the Manhattan before before being found fast asleep on a Harlem subway station bench, cops said.

Zhaundu Bradley walked out of his family’s East 19th Street apartment at around 11 a.m. Monday after becoming upset with his parents, sources said.

Bradley’s mom and dad were allegedly napping when the boy walked out of the apartment and went down into the subway, cops said.

A doorman at his building said he watched Bradley waltz out the door but didn’t bother to stop him.

“I saw him leave,” he said. “He looked, you know, happy. He’s just a kid.”

The doorman, who wouldn’t give his name, said it wasn’t his responsibility to stop people.

“How am I gonna stop people? I’m not a cop,” he said. “I never ask where you’re going. The person can turn around and say ‘What [business] is it of yours?’”

From there the boy proceeded to ride the the train around the city before a straphanger found the boy asleep on a subway station at 116th Street and Lenox Avenue, cops said.

Bradley was returned by police to his parent’s home unharmed.
