DULUTH — Police have arrested six women on gambling-related charges after officers broke up a gambling operation based out of at least two homes in a quiet suburban Atlanta neighborhood.

Gwinnett County police tell WSB-TV they got an anonymous tip from someone who was upset about the amount their spouse was gambling at one of the homes. When officers arrived, they discovered gambling machines.

Police seized four gambling machines and more than $15,000 in cash and arrested the woman they say ran the operation.

Information there led them to another home, where they found another six machines and made five more arrests.

Police say men were allowed inside but it appears only women could gamble.

Police say they don’t know if the alleged operations spread beyond the two homes. The investigation continues.
