The protests started peacefully on October 8, forcing the government to ban SARS and take other actions to redress injustices of the past as demanded by protesters.
The government directed all states to set up victim support funds to compensate victims of SARS brutality as well as set up judicial panels to listen to complaints.
But the protests worsened on October 20, degenerating into violence across all parts of Nigeria.
Nigerian authorities have imposed a curfew in eight more federal states as troops are deployed to curtail further violence in which scores of people have been killed.
The new move followed a 24-hour curfew imposed on residents in the commercial capital Lagos as officials tried to curtail rising violence that marked the protests against Special Anti-Robbery Squad (SARS) of the Nigeria police.
