Basically there are 2 rival factios of the Chukchansi tribe that have been fighting over control of the casino. The "losing' faction, ousted since August, decided to show back up with guns and storm the place over the weekend.
The casino is now closed until further notice.
It's located in Coarsegold, which is just south of Yosemite National Park. The casino is pretty much the only happening thing in Coarsegold. I stayed there about 10 years ago and was not impressed.
