PALM BEACH (CBSMiami/AP) – Things got heated at a Walmart store in Royal Palm Beach when an unmasked man pulled a gun on a masked shopper in an apparent confrontation over wearing a facial covering.

The store’s security video shows the unmasked man pushing an older man in a wheelchair through the store on Saturday afternoon, according to the Palm Beach County Sheriff’s Office. The man in the wheelchair pulled a red neckerchief over his mouth in the store.

In the video, a young girl reaches for the masked man’s hand to pull him away. Another person is seen trying to intervene.
