A group of exotic dancers is suing some of Los Angeles' biggest men's clubs, saying the businesses are stripping them of cash.

Attorney Patrick Manshardt filed the lawsuit Wednesday in U.S. District Court on behalf of four dancers. The suit names 19 clubs, saying they're violating federal and state law by not paying the dancers any wages and taking up to 60 percent of their tips.

Manshardt says the strippers are employees of the clubs and are being cheated out of money. He says the IRS and state of California also are being shortchanged because they aren't getting paid payroll taxes.

But Roger Diamond, an attorney who represented six of the clubs five years ago against a similar claim, says the women are contractors and not subject to employee wage law.
