HARTFORD, Conn. (AP) _ The tribes that own Connecticut’s two casinos are taking another step in their bid to open a third casino north of Hartford.

The Mashantucket Pequot and Mohegan tribes hosted a signing ceremony Thursday, Sept. 10 in Hartford to formalize their partnership.

law passed this year allows the tribes to request proposals from cities and towns that might be interested in hosting a casino.

The tribes are hoping to open a casino along the Interstate 91 corridor in north-central Connecticut to compete with the planned MGM Resorts casino in Springfield, Massachusetts.

The tribes own and operate Mohegan Sun and Foxwoods Resort Casino, tribal casinos located on sovereign land. A new casino would be subject to a slightly different set of rules as a commercial property outside of tribal land.
