The elite force Rapid Action Battalion (RAB) personnel have arrested the chief coordinator of the banned militant outfit Jama'atul Mujahideen Bangladesh (JMB) and his four associates in Sadar upazila rail station of Sirajganj on Friday morning.
The arrested persons were identified as Ehsar members of JMB Abdun Nur, also coordinator of Chapainawabganj district JMB, Nur Islam and Nuruzzaman Arif and Gayre Ehsar (hidden cadre) members Md Abul Kalam Azad and Faruk Ahmed.
Forty-nine primary detonators, 26 electronic detonators, four time bombs, 10 kilograms of power gel, 155 different kinds of circuits, 55 jihadi (provocative) books and one power regulators were seized from their possession, he said.
The militants had planned to explode the explosives at different areas to show their existence and strengthen their networks, he said during a press conference on Friday.
Abdun Nur is the main coordinator of the banned militant outfit who maintained close connection with his followers now in jail and in hiding, the Rab official claimed.
Acting on a tip-off a RAB team conducted a drive at the Syed Mansur Ali Railway Station around 2:30am Friday and detained them.
Carrying the explosives, they were going to Joydebpur of Gazipur from Chapainawabganj by train, he said.
Indian intelligence, investigating the Burdwan bomb blast case, claimed to have uncovered a JMB plot to assassinate Prime Minister Sheikh Hasina and BNP chief Khaleda Zia.
In October, police said the banned outfit was planning a massive attack across Bangladesh to grab international headlines. India's National Intelligence Agency said it unearthed a major JMB plot to carry out attacks in Bangladesh.
However, the Bangladesh government earlier asked its Indian counterpart to share more information of the October 2 bomb blast at Burdwan district in the West Bengal for which the Indian media pointed finger to "militants from Bangladesh".
The Ministry of Foreign Affairs sent a note verbale to the High Commission of India (HCI) over the blast.
The explosion at the Burdwan house killed two suspected militants -- Shakil Ahmed and Sovan Mandal -- and left another one named Hasan Saheb injured. Three people?Rajira Bibi alias Rumi, Amina Bibi and Hafez Mollah alias Hasan -- were arrested after the blast.
New Delhi also agreed to share information with Dhaka about the recent bomb blast at Burdwan in West Bengal as Indian media point the finger at "Bangladeshi militants" over the explosion.
Meanwhile, India's National Investigation Agency said the accused persons in the Burdwan town blast case and their associates were members of Jama'atul Mujahideen Bangladesh.
"NIA is conducting a thorough probe into the activities of JMB covering all aspects, including the funding of terror activities," the statement said.
It said NIA was also considering announcement of cash rewards for any information leading to the arrest of the absconding accused of the case, including JMB members from Bangladesh.
