The Anti-Corruption Commission had filed the case with Tejgaon Police Station in 2007, accusing Khaleda and 10 others of abusing power to award a gas exploration and extraction deal to Canadian company Niko during her tenure as the Prime Minister.
Brigadier General Abdullah Al Harun, Director of Bangabandhu Sheikh Mujib Medical University (BSMMU) -- a government-run medical university cum hospital -- told journalists on Thursday that she was released from hospital as the medical board formed for her treatment gave her a discharge certificate.
He said that her physical condition was now stable.
Khaleda was then taken to the BSMMU from Dhaka Old Central Jail.
She has been in jail since February after a court sentenced her over the alleged embezzlement of foreign funds.
