14 of 15 members of the Lac du Flambeau Chippewa Band have been released on signature bonds following a 14-hour sit-in Wednesday at the Tribal Center.
Bond was set at $250 each.
The Vilas County Chief Deputy Sheriff says the group was arrested on tentative charges of criminal trespassing.
They are expected to be back in court May 7.
Police say the protestors surrendered peacefully shortly before 4 p.m. Wednesday after federal officials agreed to investigate their allegations of corruption among tribal leaders.
