Torab Ali, who was acquitted of the charges in BDR carnage recently, died at Dhaka Medical College Hospital yesterday, aged 80.
Torab was hospitalised on Wednesday with cardiac complications, Mohammad Hanif, a guard of Dhaka Central Jail, told The Daily Star.
On November 5, 2013, a lower court sentenced him to life term imprisonment on the charge of plotting the BDR mutiny. The High Court acquitted him from the charges on November 27 last year.
He was in jail custody as the HC order did not reach the jail authorities, Hanif said.
His body was kept at Dhaka Medical College morgue, said Sub-inspector Bachchu Mia, in-charge of DMCH Police Outpost.
Torab was a ward-level Awami League leader in Hazaribagh.
Earlier on May 3, 2015, Nasiruddin Ahmed Pintu, a BNP leader, who was given the same jail term by a lower court on the same charges, died of cardiac arrest at Rajshahi jail.
As of yesterday, 12 accused were acquitted and two died.
On November 27 last year, the HC confirmed death penalties for 139 out of the 152 accused, who were given capital punishment by a lower court.
In the verdict, the court upheld life imprisonments of 146 out of 160.
In 2009, 74 people, including 57 army officers, were killed in the BDR mutiny.
