"He has been shifted to a cell (earmarked for death penalty convicts) at the (suburban) Kashimpur Central Jail," a prison official told reporters, a day after the International Crimes Tribunal sentenced Chowdhury to death.
Jailer Mojibur Rahman said Chowdhury was transferred to Kashimpur under heavy security from Dhaka Central Jail last night to be kept in isolation in a small room called the "condemned cell" to await execution, which is expected after a few legal procedures.
The tribunal yesterday sentenced Chowdhury to death, saying nine out of 23 charges of "crimes against humanity" against him were proved "beyond reasonable doubt".
Chowdhury's lawyers have said an appeal against the verdict would be filed in the Supreme Court.
