Richmond Police say 49-year old Denise Reed was holding late night card games in her home on Derwent Road, and was keeping a cut of the money.
She and five others were arrested when detectives searched the house.
We're told a home break-in and a robbery, that appeared to be a set up, led police to the illegal gambling operation.
Detectives interviewed neighbors. One woman, who didn't want to be identified, says Reed's house was always busy.
