Nepal police arrested former Prime Minister Khadga Prasad Oli and former Home Minister Ramesh Lekhak early Saturday in Kathmandu for their roles in a violent crackdown during political protests last September.The high-profile detentions follow an investigation by an interim government commission that recommended ten-year prison sentences for the two politicians and the police chief at the time of the unrest.The current administration maintains that holding previous leaders accountable for the deaths of seventy-six protesters is necessary for national stability
