Forget Thursday night poker with the guys.  For these Duluth women it was "ladies night" with a one-armed bandit.

Gwinnett Police now confirm to News/Talk WSB that at least six women have been arrested and charged in what appears to be an all female gambling ring.

Investigators carried out raids on two houses in Duluth seizing ten slot machines and nearly $20,000 in cash.

The first raid Monday on Michael Circle led to the arrest of Mi Hui Yi, 55.  She's charged with keeping a gambling place, commercial gambling, and possession of gambling devices.

A second raid at 3927 Old Norcross Road led to the arrests of five other women.   Police identified them as:  Mi Hyang Huh, Shirly Kim, Chung Suk Han, Young Suk Han and Sung Hee Choi.

Investigators say house rules were strict.  While men could attend, they could not participate. 

Neighbor Cindy Murray tells WSB’s Sandra Parrish she suspected something illegal was going on, but not gambling. 

“For about two years there’s been a lot of traffic in and out, in and out and it was mainly always just women,” she said.  Often the women traveled in limousines or town cars.

 Murray says at one point this spring she noticed two slot machines in the cul de sac in front of the home but thought the residents were delivering them somewhere else.

She said she realized during the raid what was actually going on.  “We saw all the police come down and we saw the slot machines come out,” says Murray.
