BNP chairperson Khaleda Zia has been taken back to jail after having medical tests at Bangabandhu Sheikh Mujib Medical University (BSMMU).
She left the hospital around 1:30pm and reached the old central jail at 2.45pm on Saturday.
An ambulance carrying her reached the hospital around 11:30am for some medical tests. The four-member medical board was present during conducting the tests.
Earlier on April 1, a four-member medical board formed for the treatment of the BNP chief examined her at old central jail.
She fell sick in the jail on March 29 and postponed a scheduled meeting with its secretary general Mirza Fakhrul Islam Alamgir.
On February 8, Special Judge's Court-5 of Dhaka sentenced Khaleda to five years' rigorous imprisonment after it had found her and five others guilty in Zia orphanage trust graft case.
The court also awarded jail sentences to Tarique Rahman, now the acting chairman of BNP, and four others for 10 years and fined them Tk 2.10 crore, saying that all the six convicts have to pay the fine in equal amounts.
The Anti-Corruption Commission filed the graft case with Ramna Police Station in July 2008, accusing the six of misappropriating over Tk 2.1 crore that came from a foreign bank as grants for orphans.
