"We sent Mr Jalil to a prison cell as our physicians who had checked him said chest pain is not a good sign for a person having a pacemaker installed in his body," Deputy Inspector General (Prisons) Maj Shamsul Haider Siddique told The Daily Star last night.

He said Jalil complained of chest pain soon after a Dhaka court had ordered to send him to Dhaka Central Jail at 5:15pm following completion of Jalil's four-day remand.

The AL general secretary was admitted to the hospital's prison cell at 8:45pm. He was taken to the coronary care unit about two hours into his admission to the hospital.
