CHARLOTTE, N.C. Authorities have arrested six women and were searching for 10 others as part of an investigation of indecent exposure at strip clubs that one club owner said was a waste of law enforcement resources.

The Charlotte Observer reported Friday that Alcohol Beverage Control officials said the topless dancers are charged with violating a state law that prohibits them from performing nude.

The arrests are part of a six-month undercover investigation into eight adult-entertainment clubs in Charlotte. Most of the clubs involved are operated by M.A.L. entertainment, a company owned by Charlotte businessman David “Slim” Baucom.

“They know that they’re not allowed to expose themselves and they did,” said Michael Crowley of Mecklenburg’s ABC commission. “You’re not allowed to remove your bottom.”

Crowley said the women removed all of their clothes during table dances on the main floor and in semi-private areas, roped off for customers who pay extra for special dances.

Agents said Baucom cooperated with authorities and provided the real names of some of his dancers.

Chris Fall, owner of the Paper Doll Lounge, said the investigation is a waste of taxpayer money, particularly in tight financial times. Authorities said an ABC agent and a Pineville police officer conducted the investigation.

“The government, they’re bad on money and they’re coming after us,” Fall said. “Paying (agents) to go to strip clubs … and have a good time.”

The clubs could face disciplinary action by the state ABC commission, which controls licensing for businesses that sell alcohol.

Crowley compared the operation to other ABC stings, in which the commission sends minors into gas stations and grocery stores to try and buy alcohol and cigarettes.

“We want to make sure that these adult entertainment establishments are following the law,” Crowley said. “That’s our job.”
