After repeated disruptions at Tuesday nights city council meeting by supporters of concerts at Metropolitan Park, Council President Bill Bishop cleared the room.
During public comment, "public displays" like signs, boos, shouting and applause are prohibited under council rules.
The public was sent out of council chambers into the Lynwood Roberts and Donald Davis rooms and brought in to speak three at a time.
After about 90 minutes, Bishop let everybody back in, but reminded them to abide by the rules.
