Another accused in the same case, Lieutenant General (retd) Chaudhary Hasan Sarwardy, completed his eight-day remand and is currently in jail.
The DB of Dhaka Metropolitan Police is monitoring the investigation.
According to a DB source, Mia Arefi could not be taken on remand due to lack of permission from a higher authority.
Meanwhile, the information gathered during the remand interrogation of Chaudhary Hasan Sarwardy is under investigation.
However, a source associated with the investigation says that the progress of the case has stopped. Officials at DB’s Motijheel division declined to provide details on the progress of the case.
