Federal immigration agents conducted a traffic stop and arrested three men Saturday near the Akimel Smoke Shop on Gila River Indian Community land off Interstate 10 at Riggs Road. According to the Community, the men were not enrolled tribal members or residents. Gila River Police responded to the scene but were not involved in the stop, and tribal leaders said the incident raises concerns about the community's sovereignty. Tribal leaders issued an advisory urging members to carry tribal identification and know their rights when approached by federal agents.
