Family sources said that Wazed Miah had been suffering from heart ailments for a long time and was rushed to hospital at around 12:30pm following "acute chest pain."

"Condition of Wazed Miah is stable now and it was just a chest pain, not an attack," Cardiologist Dr ABM Sohrabuzzaman, under whom Dr Wazed is being treated, told The Daily Star at around 5:30pm.

The physician, who had been treating Wazed for the past 17 years, also said that his patient had been suffering from heart diseases and diabetes. Besides, he had high blood pressure, gout and kidney problems.

Apart from physical problems, Wazed is suffering from bipolar disorder (a mood disorder) coupled with dementia (losing memory gradually), said Dr Sohrabuzzaman.

Relatives of Wazed hospitalised him fearing his condition might worsen hearing the news of arrest of Sheikh Hasina, he said.

The physicians are cautious and are not saying anything on the Hasina issue to Wazed to help reduce his mental stress, Dr Sohrabuzzaman said adding that he would be sent home considering his mental, physical and familial situation.

Awami League chief Hasina, also a former prime minister, was arrested from her Sudha Sadan residence at Dhanmondi yesterday morning in an extortion case and sent to a specially designated prison in the parliament-building complex.
