The Rapid Action Battalion (RAB) arrested Huji-B founder and death row convict Mufti Abdul Hye on Wednesday after 17 years of hiding.
Mufti Abdul Hye is a death-row convict of Gopalganj's Kotalipara and Dhaka Ramna Batamul bomb attacks.
RAB's Media and Legal Wing director Commander Khondker Al Moin made the disclosure about Hye’s arrest on Thursday at a press conference.
The top Islamist militant was also given a life sentence in the 21 August grenade attack case.
The elite force arrested the top militant from Fatulla in Narayanganj on Wednesday.
According to the RAB, Mufti Hye was also the founder Ameer of militant organisation Harkat-ul-Jihad-al Islami Bangladesh (HuJi-B).
Mufti Hai started living in Narayanganj in 2009 after changing his name.
He not only changed his NID card but also NIDs of all of his family members to avoid arrest.
While in Narayanganj, he hardly went outside. Thus he was hiding since 2006.
An accused in at least 13 cases, the top militant was sentenced to a life term in two other cases.
RAB said that Mufti Hye first went into hiding near his father-in-law's house in Gouripur upazila of Cumilla after his involvement in the attacks surfaced in 2006. He later shifted to Narayanganj.
He was the founder and editor of the newspaper the Monthly Jago Mujahid. The office of the controversial newspaper was in the Khilgaon area in the capital Dhaka. His fellow militants including Mufti Hannan held meetings there.
The government banned the newspaper in 2000. He was arrested that year but was released after two months on bail.
Earlier on April 14 last, Mufti Shafiqul Islam, another death-row convict of Ramna Batamul's Barshabaran bomb attack case and life-term convict of the August 21 grenade attack case, was arrested from Bhairab in Kishoreganj district.
On July 20, 2000, police recovered a 76-kilogram bomb from near a shop adjacent to Sheikh Lutfur Rahman Govt High School, where Sheikh Hasina was scheduled to address a rally on July 22 the same year.
On July 21, 2000, another bomb weighing 40-kg was recovered from Gopalganj Sadar.
Ten people had been sentenced to death in this incident, all of who had connections to Harkat-ul-Jihad.
On the morning of Pahela Baishakh, April 14, 2001, at least 10 people were killed and many injured in a bomb blast during a cultural programme at the capital's Ramna Batamul.
