The secretariat has been made off-limits to journalists after evening, what security said on Tuesday.
However, officials at the Home Ministry said they were not aware of the move and said the decision was not taken from its office.
Restriction measures were imposed upon orders from police Additional Deputy Commissioner Moshiur Rahman for security reasons, security said.
Journalists were barred from entering the secretariat premises on Tuesday evening. This Dhaka Tribune reporter was inside secretariat premises during this time.
He came down after his colleagues waiting outside informed him of the situation.
During this time, armed police Sub Inspector Farazul Haque, stationed at the gates, informed him of the orders from police.
The area’s ADC Moshiur Rahman did not pick up his cell phone when journalists repeatedly tried to reach him to know details about the matter.
Home Secretary CQK Mustaq Ahmed later said that he was not aware of the move and he did not know why such orders were issued.
