Awami League leader of Dhaka city Torab Ali is among the persons who were acquitted by the High Court in BDR mutiny case.
Most of the convicts were jawans or non-commissioned officers of the erstwhile border force Bangladesh Rifles (BDR).
Those sentenced to life in prison by the lower court included two politicians from the two major parties of the country.
They are Torab Ali and former BNP MP Nasiruddin Ahmed Pintu. The BNP leader died in jail on May 3, 2015.
The trial court had also fined Torab Ali, a former president of the ruling party's Ward 48 unit in Dhaka's Hazaribagh, Tk 500,000.
He was supposed to serve an additional 5-year term in jail if he had failed to pay the fines.
Now, the High Court has acquitted him of the charges in the case.
The mutineers killed 74 people, including 57 army officers, at the Peelkhana headquarters of BDR on Feb 25-26 in 2009.
