Chilling video captures the moment a quick-thinking 10-year-old Pennsylvania boy eluded a woman who was trying to lure him away — by telling a store clerk to pretend she was his mom.

Sammy Green was walking home from school in Pottstown on Friday when the woman began following him on High Street, CBS News reported.

“Started walking with him and asking him where his family was, asking where his dad was,” the boy’s dad, Sam Green, told WPVI.

“She said she probably knew me and was going to Wawa and that he was supposed to go with her and he could get anything he wanted,” he said, referring to a convenience store.

Sammy recounted how the woman peppered him with bizarre questions and made him uncomfortable.

“She was like, ‘I’m going to Wawa. Are you going there? What are you getting from Wawa? Where’s your family at?’” the boy told CBS News.

The stranger also offered to buy the fourth-grader food before a security camera inside Dani Bee Funky, a store he’s familiar with, captured them walking by.

Sammy is seen walking into the store and going to the cashier, 17-year-old Hannah Daniels, and whispering in her ear while the woman stands outside.

“He was like, ‘Pretend like you’re my mom,’” Hannah told CBS News. “And I was just like, ‘All right, go to the back.’ He didn’t want to leave my side.”

The video shows a poised Hannah walking to the door and locking it as Sammy stands behind her. The woman promptly walks off.

“I was still shaking when I was in here,” Sammy told the news outlet after the scary episode, which he ended by following what his dad had taught him about strangers.

“When we were watching that video, I cried every time I saw it,” Green told WPVI.

Police later tracked down the woman and said she was getting treatment for mental health issues.

Store owner Dani Small praised Sammy and Hannah for their clever actions.

“I am very proud of her. Hannah is a 17-year-old young lady. She did everything correctly,” Small told WPVI.
