Kolkata: The explosion outside the NIA office in Kolkata has once again brought into focus the reach and spread of terror network in West Bengal.
With the NIA said to be close to cracking the Burdwan blast case after it arrested several key operatives of the Jamaat-ul Mujahideen Bangladesh (JMB), reports said that investigators suspect the blast outside NIA office was carried out as a warning against further probe.
The blast – though a minor one – may have been meant as an intimidation, reports added.
The blast occurred around 7:30 pm yesterday evening outside the NIA camp office, situated in the Bidhannagar area in the Salt Lake suburb of the city, when two crude bombs were thrown from a car passing by the camp office area.
Reports said no explosives were found at the spot and the material used could be a firecracker. No one was injured in the incident.
Among the suspects in NIA's custody is the alleged mastermind of the Burdwan terror module Sajid alias Sk Rahamatulla. He was nabbed last Saturday from near Kolkata airport by the West Bengal Police and was subsequently handed over to the NIA.
Sajid - investigators said he used to taught in madarsas and impart jihadi ideology- later admitted before a court that he served several years in Bangladesh jails and fled to India earlier in the year.
Sajid's close associate and key 'jihadi motivator' Zia-ul-Haque and key operative Amjad Sheikh are also in NIA's custody.
Sheikh, alias Kajal, a resident of Birbhum district of West Bengal, is alleged to be the main person who used to procure material, meant for making improvised explosive devices, from open market.
The accidental bomb explosion in a house in Khagragarh had left two suspected JMB militants dead and another injured and broke the lead on the most sensational jihadi terrorist conspiracy in the state in recent times.
Shakil Ahmed died on the spot and another person Sovan Mandal died in hospital. Both were suspected to have links with JMB. Another person - Hasan Saheb, who was also injured in the blast, gave some information which led to the arrest of six people in Assam. However, only two women including the wife of one of the dead man, was useful in giving some sketchy information about the blast conspiracy.
