Police are searching for a man they said tried to snatch a four-year-old child from his stroller Saturday on Staten Island — right in front of the boy's mother.

It happened around 5:15 p.m. on Olympia Boulevard near Mapleton Ave. in Midland Beach.

The city police department said a man got out of a black Toyota Prius that pulled up alongside the child and his mother and tried unsuccessfully to remove the child from the stroller.

The man then fled the scene. The mother and child were not hurt.

The investigation is ongoing. A description of the man was not given.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-8477, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com
