MOUNT KISCO, N.Y. (CBSNewYork) — Police in Westchester County were searching late Thursday for a suspect who tried to lure two girls into his car.

As CBS2’s Dave Carlin reported, the separate incidents happened about an hour apart on Wednesday in Mount Kisco. The suspect’s targets were girls ages 11 and 12 years old.

Yellow road signs reading, “Slow, children at play,” appear at the top of Langeland Drive in Mount Kisco — advertising how family-friendly community is.

But at 2:30 p.m. Wednesday, one driver did not just slow down, but stopped outside a home where a girl was inside looking out the front window.

Police say the stranger, while still in a dark-colored four-door sedan, motioned for her to join him.

“It’s extremely frightening,” said neighbor Valentina Cardile.

Cardile knows the girl, who knew better than the leave the house. Instead, she told her parents and they called police.

“She’s, you know, a very smart little girl,” Cardile said. “You think you move here to these quiet neighborhoods and you’re going to be safe. This just reminds us — you need to be aware of where your kids are at all times.”

Police said the girl described the man as older, but could not say much more about him. Police said he was not done.

The second incident happened about an hour later a mile away on Grove Street near the busy center of town. An 11-year-old girl was walking home from school when a when a car pulled up alongside her.

The driver gestured for her to come over. She wisely kept going and ignored him, but the car followed slowly behind.

So police said she ran, made it home, and told her mother.

“Every child today has to be educated by their parents about caution when it comes to strangers, unfortunately,” said Rita Sherman of Mount Kisco.

“The police need to be around, especially these streets, because there are a lot of kids over there,” said Kelly Pelaz of Mount Kisco.

Mount Kisco police told CBS2 that extra patrol units are out, and around schools when they let out, as police continue to hunt for the mystery man.
