In yet another breakthrough in the October 2 blast case in West Bengal's Bardhaman, the members of Indian National Investigation Agency (NIA) arrested the fourth key suspect, Shahnoor Alam.
Shahnoor, alleged to be the financial brain of Jamaat-ul-Mujahideen Bangladesh (JMB) terror group, was picked up from Nalbari district of Assam along with the help of central security agencies on Friday evening.
Other three key suspects, mastermind Sajid alias Sheikh Rahamatullah, Myanmar national Khalid Mohammed and Abdul Hakim, who were earlier arrested by the NIA are already in judicial custody.
The NIA, whose probe into the blast case received a boost after the arrest of Sajid, had been tailing Alam for quite sometime after his name surfaced in the call records and interrogation of the arrested accused person, reported Zee News.
The investigating agency had last month arrested his wife but Alam had been on the run since the blast.
Alam, alias Doctor hails from Chatala village Barpeta district in Assam, is alleged to have arranged the money for the Indian modules of JMB.
NIA had also declared a reward of Rs500,000 for anyone providing any information about him.
So far, half a dozen have been arrested in India's West Bengal in connection with the blast and two others for supplying Students Islamic Movement of India (SIMI) cards.
Khalid Mohammed, was arrested from Hyderabad. Nine others were caught from Assam.
In Bangladesh, six people were nabbed for their involvement in the blast while three are behind bars as accomplices.
The accidental blast took place inside a house in Khagragarh killing two JMB militants and injuring another. Probing the blast, the NIA has arrested several people including Bangladeshi nationals.
Soon after the blast, the inmates tried to pass it off as a cooking gas cylinder explosion. For days, the West Bengal government downplayed the incident.
