It is the first time in 21 years of law enforcement that Det. Dennis Harris ever got a call like this one.

A woman, Erica Porras, reported that when she stopped by Wal-Mart to try on some discounted shoes, a man had approached her with an offer of assistance. He informed Porras that he was in training to be a foot doctor and wanted to help her find comfortable shoes.

The man had the 37-year old mother of two remove her shoes and socks and then he examined her feet, photographed them and then allegedly licked her toes and stuck her foot in his mouth. Porras balked. The man begged for forgiveness, offering to pay for her groceries if she wouldn’t report him. She called the cops anyway and he ran.

The North Carolina police were able to track the man, Michael Brown, and charge him for the toe molestation.

Brown is also being investigated on suspicion that he tried the same stunt at another Wal-Mart earlier in the day. According to the AP, he had told a woman that he was conducting a survey on the feet of different races and nationalities. He convinced the woman to take off her shoes, but she left when Brown allegedly asked her to remove her socks.
