The arrest of outlawed Islamist militant outfit member was made from Kamlapur Rail Station area in Dhaka early Saturday, says DB Deputy Commissioner (media) Masudur Rahman.
A press briefing held at DMP media centre regarding this matter around 12noon, where DB Joint Commissioner Abdul Baten said arrested Khairul Islam alias Jamil alias Rifat alias Fahim alias Jisan participated in the murders of Dipan and Niloy.
During primary interrogation, Khairul, a member of ABT intelligence unit, pleaded his role in the killings, he added.
The commissioner termed Khairul a top leader of Ansar al-Islam, saying he joined ABT from 2013 and in the next year he met the outfit's big brother Sayed Ziaul Haque, a sacked army major for his involvement in a failed coup in December, 2011.
The ABT man was assigned to collect information about Dipan and Niloy from January to August last year and he reported it to maj Zia who ordered his operational wing to execute the killings.
Abdul Baten continued: “Seeing CCTV footage, Khairul has identified four people involved in blogger and secular writer Avijit killing and we are analysing the information.”
On September 26, Khairul met maj Zia alias Eshtiaq on the outskirts of Dhaka, he added.
