Rasel Bin Sattar Khan, arrested for spreading online the audiovisual message purportedly of al-Qaeda chief Ayman al-Zawahiri, will be brought to the capital from Tangail today for interrogation at the TFI cell.
He would face the grilling at the Taskforce for Interrogation (TFI) cell by experts of different law enforcement agencies, said Hasibul Alam, additional superintendent of police in Tangail.
Rasel, 21-year-old student, was picked up in a raid on a private mess in Majhipara of Tangail town around 2:00am Tuesday. During a press briefing at the Rab headquarters later in the day, he admitted circulating the clip through his Facebook page and blogs.
The youth was quizzed by police after a local court on Wednesday put him on a 10-day remand in a case filed under the Information and Communication Technology (ICT) Act.
ASP Hasibul Alam told our district correspondent yesterday that during interrogation, Rasel gave them some important information. He, however, would not disclose it now.
Contacted, Rab Director General Mukhlesur Rahman said intelligence agencies were trying to find out the first upload point of the message for verifying its authenticity and to identify the persons behind it.
“The authorities of sites like Google and Yahoo can provide us information about the first upload point of the message,” he said.
"Intelligence agencies have asked the Bangladesh Telecommunication Regulatory Commission to gather information from them [Google and Yahoo].”
Mukhlesur added the probe would take time. “Primarily it has been learnt that two web sites -- one based in Pakistan and the other in the US -- uploaded the message.”
