Surveillance footage from inside a Brooklyn bodega where a white woman called the cops on a 9-year-old boy, claiming he grabbed her butt, shows the kid didn’t lay a hand on the lady.

The video shows Teresa Klein standing at the counter of the Sahara Deli Market in Flatbush on Wednesday, paying for two bags of cat litter, as the boy walked past her to exit the store, followed by his mother.

The boy was carrying a backpack and a large plastic bag from Cookie’s department store across the street, and the bag appears to brush against Klein as he passes.

Klein immediately turns around and begins arguing with the family.

A deli worker told The Post on Friday, “He was walking out with his mom and accidentally brushed up against her. His mother was right behind him.”

Cellphone footage of the ensuing encounter, in which Klein called police on the boy while he bawled, went viral this week, earning Klein the nickname “Cornerstore Caroline,” an apparent reference to the moniker given to some other white women who called the cops on African-Americans over apparently minor incidents.

“His mother was saying she was going to call the police. Me and my son were recording it, thinking if the white [woman] call the police, who knows, maybe the mom could go to jail,” said customer Joni Torian, who witnessed the dispute.

“The mother was right behind him when she says he grabbed her very flat behind. Ain’t no mama gonna let her child sexually assault a woman. [The customer] started yelling, ‘Miss, you need to watch your son, he just grabbed my ass.’ It was kind of funny at first, but then she was saying, ‘I will call the cops.’ ”
