TROY, Mich. (FOX 2) – Sophia Simpson, 10, is still recovering after an adult woman randomly slammed her head into a cookie display at Somerset Mall in Troy.

The incident took place last Friday as Sophia waited in line for a cookie from Mrs. Fields at the mall, according to police. She was there with a group of friends and one of their dads.

“She took her hand in the back of my neck and slammed it into the glass,” Sophia said. “The car ride back, oh my gosh, it was terrible. I was so dizzy. I was actually really tired too.”

The attacker is allegedly 25-year-old Reanna Valentine of Detroit.

“I checked my phone and then… that woman came up and hit my head against the glass,” Sophia said. “I started crying and then she turns around, she starts laughing at me, and then she puts on her mask and runs away.”

“Like why? I don’t know why, I mean i didn’t do anything to her,” she continued.

Police said the incident seemed to be “unprovoked and for no apparent reason.”

Surveillance video shows that Simpson did nothing wrong to provoke Valentine.

“They reviewed the footage from when the woman first walked in the mall all the way to where the incident occurred, and they said there was nothing,” Sophia’s father, Nick Simpson. “There’s no explanation for why she did this.”
