Addressing a presser today, Fawad played a clip of the alleged call, in which a male voice can be heard asking the recipient of the call to delete what is presumably a social media post. "You will be picked up by 5pm tomorrow," the caller can be heard saying.
"There are only two big [security] agencies," Fawad said.
He added that Chief of Army Staff Qamar Javed Bajwa and Inter-Services Intelligence (ISI) Director General Lieutenant General Nadeem Anjum have recently issued orders for their institutions to stay away from "such matters".
"I am hopeful these directives will be implemented. If people from the Intelligence Bureau (IB) are doing this, then I would urge their head to look at their institution."
"Pakistan is not Burma. Fear does not last forever," he said, adding that martial law had been imposed in the country four times but had also subsequently ended.
"If you think you can rule over Pakistan on the basis of power, this does not happen here. There will be retaliation, the people will stand up."
