On Friday, police stopped a group of protesters from gathering, bundling them into buses. Several nearby metro stations remained shut amid tight security.
Though police released many of those detained on Friday, they charged several of them with allegedly violating orders banning mass gatherings in Delhi, according to a police source.
Critics say a nationwide voter-verification exercise launched last year has led to millions of eligible voters being removed from electoral rolls.
The commission, long regarded as one of the country’s most trusted institutions, says the exercise is intended to remove duplicate, deceased or ineligible voters.
On Friday the commission directed officials to register newly eligible voters and those omitted from electoral rolls.
