Foyzur Rahman Faizul, who stabbed noted author Professor Zafar Iqbal at Shahjalal University of Science and Technology (SUST), has admitted that he used the smartphone application Telegram for communication.
However, during initial interrogation, the attacker claimed that he cannot remember his ID and password for the app.
Faizul has also given contradictory information to law enforcers regarding his frequent disappearances from his home in Sylhet.
Officials concerned with the probe of the attack on Zafar Iqbal have a strong suspicion that the youth has connections with at least one militant group.
One of the officials, who interrogated Faizul, has disclosed the matter to the correspondent.
Telegram is a cloud-based instant messaging service that offers its users secure electronic communication through a custom encryption protocol.
Militant groups operating in foreign and domestic soil mostly prefer these types of messaging apps to call and message due security reasons.
Even in Bangladesh, many arrested members of the new faction of the banned militant outfit Jama'atul Mujahideen Bangladesh (New JMB) and Ansar al-Islam were found to have been using these smartphone apps for secure communication.
According to sources, the banned militant group Ansar al-Islam has changed its organizational strategy by instructing its members to carry out militant activities in their homes, for alleviating suspicion.
However, members of sleeper cells held meetings in Markaz- which is the militant group’s code name for safe-houses.
Officials concerned have suspicions that Faizul used the Telegram app to maintain communication with an extremist group, which could be Ansar Al-Islam.
Faizul’s behavioral pattern, and information given by him during interrogation, is quite similar to the previously arrested members of Ansar al-Islam.
Law enforcers are suspecting that the youth could be a member of a sleeper cell.
Responding to a query, Additional Deputy Inspector General (Intelligence and Special Affairs) of Police Headquarters, Md Moniruzzaman said: “We have made significant progress in the investigation on the attack of Zafar Iqbal.
“It is certain that Faizul harbours extremist beliefs, but we are yet find evidence that he is a cohort, or has links with any militant groups. Investigating a militant attack is time consuming, but we are close to solving the mystery.”
