Banned Islamist outfit Allahar Dal is actively working on recruiting those who had been sacked over the Pilkhana massacre.
The organisation is also seeking to hire retired personnel from armed forces or sacked members of various organisations online as well as at rural levels.
Rapid Action Battalion Legal and Media Wing Director Lieutenant Colonel Emranul Hasan disclosed the information at a media briefing held at Karwan Bazar in the capital on Monday (Aug 19).
On late Sunday (Aug 18) night, RAB-03 detained four militants of Allahar Dal in Hatirjheel of Dhaka.
Those arrested are Ibrajit Ahmed Hero, 46, Abdul Aziz, 50, Md Shafiqul Islam Suruj, 38, and Md Rashidul Islam, 28.
The RAB also seized mobiles, pen drives, hard discs, credit cards, check books and books from them.
During primary interrogation, the suspects had claimed themselves to be members of Allahar Dal or Allahar Sarkar and revealed other important information, said the RAB official.
According to RAB, Allahar Dal is trying to recruit retired or sacked members of various armed forces to avoid need for training.
The outfit was established in 1995 at the leadership of Motin Mehedi who has many other aliases and helped JMB execute the Series Bob Blasts in 2004.
Motin Mehedi parted from JMB lost when JMB began to lose its organisational strength due to the crackdown of law enforcement agencies on militant units but the outfit began regrouping after Mehedi was arrested in 2007.

The outfit currently operates through an organogram similar to that of the country’s administration or hierarchy followed by armed forces. It is actively involved in recruiting members online and at the grassroots levels.
The suspects had also revealed that it had been planning to steal its leader Mehedi Motin from the law enforcement agencies when he would be taken to court on a prison van, Emranul said.
Inbrajit had revealed that he was acting as the Acting Taroka, a rank equivalent to an amir, of Allahar Dal in absence of the outfit’s Taroka.
