The Brooklyn mom whose son was targeted by “Cornerstore Caroline” last week said at a rally Monday the hardest part of the incident was having to explain to her 9-year-old what sexual assault is.

“Cornerstore Caronline,” aka Teresa Sue Klein, called the police on 9-year-old Jeremiah Harvey, who she falsely accused of grabbing her backside at a Flatbush bodega last week.

“That day, fear was placed into my child’s heart,” Jeremiah’s mom, identified by WABC as Someko Bellille, 37, said in a Monday community meeting where she spoke out about the incident for the first time.

“Having to explain to your 9-year-old son what assault is, what sexual assault means, and having to go over the term with him what racism is. And having to witness and see he’s crying all over again,” she said, according to video posted by PIX 11.

Klein’s phone call to the NYPD was captured on now-viral video and she was accused of racism by her outraged neighbors. She apologized and denied being racist.

“I don’t forgive this woman at all,” Bellille said at Monday’s meeting. “I think she was crazy. I think she had something going on with her.”

Brooklyn District Attorney Eric Gonzalez said Saturday his office is looking into the “disturbing incident.”
