LINCOLNTON, N.C. -- Police say a 31-year-old North Carolina man sucked a woman's toes at a Wal-Mart after he convinced her he was a podiatry student and persuaded her to take off her shoes.

Detective Dennis Harris said the woman agreed to try on several pairs of shoes at the discount store in Lincolnton, and that at some point during the process, the man stuck her foot in his mouth. When the woman became upset, the man offered to pay for her groceries, police say.

Harris said the man apparently tried the same thing at another Wal-Mart 15 miles away, where he told a woman he was conducting a survey on the feet of different races and nationalities.

The second woman also agreed to take off her shoes, but left when the suspect asked her to remove her socks.

Both confrontations happened Monday.

Michael Anthony Brown of Concord, N.C., was arrested Thursday night at his home. He was turned over to Lincolnton police. A Lincoln County magistrate set his bond at $50,000 on a charge of assault on a female. It's wasn't immediately known if Brown has an attorney.

According to police, Brown is a registered sex offender.
