After analysing the nature of one of Saturday’s attacks on the publishers, police also believe the assailants were ‘amateurs’.
‘Jagriti Prokashony’ owner Faisal Arefin Dipan was found fatally hacked at his office in Shahbagh’s Aziz Supermarket on Saturday afternoon.
Hours before, another attack left ‘Shuddhaswar’ publishing house’s Ahmedur Rashid Chowdhury Tutul, writer Ranadipam Basu, and blogger Tarek Rahim injured.
Dhaka Metropolitan Police Detective Branch Joint Commissioner Monirul Islam on Sunday told reporters police were ‘almost certain’ that Ansarullah Bangla Team members were involved in the murders of bloggers.
“People from groups similar to Ansarullah may also be linked to this incident (attacks on publishers),” he said.
Al-Qaeda in the Indian Sub-Continent (AQIS) through a Twitter account, purportedly handled by extremist outfit Ansar Al Islam, claimed credits for the attacks on the publishers.
Detective Monirul Islam said, “Those, who are known as Ansarullah Bangla Team, claim responsibility in this manner after conducting such incidents.”
“They claim credit identifying themselves sometimes as Seven (Ansar Al Islam Seven), or Four, or Three,” he added.
He also said: “It’s not fully true that we have arrested everyone of them (Ansarullah), nor is it true that we have not apprehended any of them. Police have made several arrests.”
Ansarullah Bangla Team chief Mufti Jasimuddin Rahmani is being tried for the murder of blogger Ahmed Rajib Haider in 2013.
Detailing the attack on Tutul at his office in Lalmatia, Islam said, “They (assailants) left two bullets. It seems they were not involved in any other incident beforehand as professional killers.”
