DALLAS -- Adult entertainment, like topless clubs, should mean just that. Except in the Dallas city ordinance covering a sexually oriented businesses or S.O.B., that doesn't say minors can't work in one. That's about to change.

“As I visit with all the council members, there is very, very strong support for that as you can imagine,” said Mayor Tom Leppert.

As News 8 first reported in late March, Dallas police found a 12-year-old girl dancing nude in Diamond’s Cabaret, a topless club in Northwest Dallas.

But police found they did not have the power to revoke the club's S.O.B. license for hiring a minor. Quite a surprise to the runaway girl's mother, after her daughter returned home.

“I really don't see why it is taking them so long to do something about it, well not do something about it, but so far as shut it down, being that they have minors working in their club,” said the girl’s mother.

Nude dancing by underage girls in North Texas happens frequently. A group that helps women escape such work says about a third start as teenagers. “But the sad story is that they come and they get involved, and they get trapped,” said Candace Cain, New Friends New Hope.

The council is moving quickly to close the loophole. “That will allow the police chief to revoke the license if there is a minor that is at these premises, that's employed at these premises, or performing at these premises,” said Mayor Leppert.

The mayor says the council will pass it next Wednesday.
