Leaders of India’s “cockroach” protest movement were detained again on Tuesday, their second detention in days, as a stand-off with authorities deepened over a contentious overhaul of voter rolls. Ashutosh Ranka and Saurav Das, two prominent faces of the youth-led Cockroach Janta Party, were taken into custody with other members after jumping barricades to enter Jantar Mantar, historically one of New Delhi’s main protest venues.
