BNP Secretary General Mirza Fakhrul Islam Alamgir was admitted to the United Hospital in Gulshan on Monday afternoon.
He was brought to the hospital around 12:30pm after he fell sick at the BNP Chairperson's Gulshan office, BNP's Media Cell member Sayrul Kabir Khan told UNB.
Fakhrul has been suffering from various health complications, including heart problems, which aggravated during his recent imprisonment.
In 2015, he was admitted to a Singapore Hospital when he was diagnosed with a block in the internal carotid artery in his neck while in prison. Since there is no treatment for this disease in Bangladesh, he has to go to Singapore every year.
He walked out of Dhaka Central Jail in Keraniganj on January 9.
On January 8, the Appellate Division upheld the High Court order granting bail to Fakhrul and BNP standing committee member Mirza Abbas in a case filed over the clash between police and the party activists at Nayapaltan on December 7 last year.
On December 9, a team of Detective Branch (DB) of police picked up Fakhrul and Abbas from their homes in separate raids in the capital, a day before the party's much-talked about rally in the capital.
Later, they were arrested in a case over the clash between police and the party activists in the capital's Nayapaltan on December 7, centring the rally. A Dhaka court sent them to jail rejecting their bail pleas.
