New York City Mayor Bill de Blasio is promising to take action against women who pose nearly naked for photos in Times Square in exchange for cash.

The practice seems to be on the rise at the major tourist attraction. Many of the women wear only body paint and a thong. They charge a few dollars to pose for photos with tourists.

Police say they can do little to stop it, and some local politicians and newspaper editorials are calling for a ban of the practice.

De Blasio says Tuesday he believes the practice is "wrong."

He didn't specify what action he would take to stop it but says that accepting money for posing topless amounts to "a business transaction" that should allow the city some oversight.
