his supporters, raising fears that Zelaya was attempting a violent confrontation. Michelletti initially denied that Zelaya had returned, but later admitted he had. Michelletti added that the return "changes nothing of our reality". Michelletti later issued a state of emergency with a curfew and asked the Brazilian government to put Zelaya in Honduran custody for trial. Brazilian foreign minister Celso Amorim stated that Brazil did not aid Zelaya's return. Security Vice-Minister Mario Perdomo ordered checkpoints on the highways leading to Tegucigalpa, to "stop those people coming to start trouble". Defense Minister Lionel Sevilla also suspended all air flights to Tegucigalpa.
