Police are looking for a man they say tried to kidnap a three-year-old boy in Brooklyn.

Police say the man was seen on video walking out of a Bensonhurst supermarket with a stroller containing the young boy Monday afternoon.

Investigators say the child was outside with his grandmother when the man went up to them.

The man then walked away with the child but the grandmother chased him down.

He abandoned the stroller with child inside before taking off on 86th Street.

The boy was not injured.
