NEW YORK (CBSNewYork) — Police say a 6-year-old boy who was kidnapped in Brooklyn has been found.

Devin Monroe was in good condition when he was found Monday by police. He was taken to Woodhull Hospital for an evaluation.

Police said the suspect, 39-year-old Emmanuel Kolajo, is in custody and is being questioned by investigators. So far, no charges have been filed.

Sources said Devin is non-verbal autistic, CBS2’s Janelle Burrell reported. Police say Devin’s mom, who knows Kolajo, dropped her son off around 6 a.m. Saturday on Madison Street for Kolajo to babysit.

When she called the man around midnight to pick up her son, detectives say Kolajo told the mother Devin was sleeping, telling her to get him on Sunday instead.

On Sunday when she tried to repeatedly reach Kolajo, there was no answer and the car that she loaned him was gone, Burrell reported.

Neighbors of the mother had been concerned.

“That’s crazy,” one woman said. “I don’t leave my daughter like that with people.”

Those who know her say she is responsible and attentive. Their Sheepshed Bay community was relieved to hear Monday that the pair was found.

Police said the investigation is ongoing.
