DHAKA , Bangladesh ( CNN ) -- Army convoys are combing areas around the Bangladeshi border guard headquarters , vowing to punish participants in this week 's bloody mutiny , which killed nearly 100 army officers and civilians , according to The New Nation newspaper . Bangladeshi firefighters continued to uncover bodies Friday of Bangladesh Rifles officers from a mass grave . More than 160 army officers were inside the headquarters of the Bangladesh Rifles ( BDR ) when the mutiny broke out on Wednesday morning , local reports said . So far , 88 bodies have been recovered from mass graves in the outskirts of Dhaka , the newspaper reported . At least 22 bodies have also been recovered from the Buriganga River after the rebelling troops dumped them down a sewer during the standoff , authorities said . The 88 found dead were among those 169 officers , the newspaper reported . Another 27 emerged from their captivity in the headquarters of the BDR , a 65,000-strong paramilitary outfit primarily responsible for guarding the country 's borders . About 200 BDR soldiers have been arrested . The mutiny began Wednesday when BDR members took dozens of their superiors hostage . It was the second day of BDR Week , when army officers and troop members from various BDR outposts along the border were in the capital for celebrations . The New Nation reported that the mutinous border guards surrendered their weapons on Thursday after the government declared an amnesty . The rebellion was spurred by years of discontent among the ranks of the BDR troops . Recruits complained their army superiors dismissed their appeals for more pay , subsidized food and opportunities to participate in U.N. peacekeeping operations . Bangladesh and its South Asian neighbors contribute the most troops to U.N. operations and the pay is far greater than the meager salary the jawans -- as the BDR troops are called -- make .
