The Australian government will hold an independent inquiry into the riots week at the Villawood Immigration Detention Centre in Sydney.
The federal police have also been asked to investigate the protests, involving up to 100 detainees this week.
A group of 22 detainees are being questioned in a prison while another group is continuing the rooftop protest on Friday.
Prime Minister Julia Gillard has condemned the riots, which come just weeks after protests at the Christmas Island detention centre, AAP reports.
Ms Gillard told reporters in Tokyo that anybody who thinks violence will help their visa applications are wrong.
The riot has also fuelled fears in southern Tasmania where the federal government wants to build another immigration detention centre.
