Kolkata: National Investigation Agency (NIA) special DG N Wassan arrived here on Tuesday to review the investigation into the Burdwan blast case.
Wassan held meetings with the officials who are involved in the investigation, an NIA official said.
NIA was handed over the investigation into the Burdwan blast case by the Centre from the West Bengal CID after international terror links were found into the matter.
The NIA had yesterday taken two terrorists -- Sajid and Hakim -- arrested in connection with the blast to Beldanga area of Murshidabad district to identify the places from where they used to operate.
A large number of IEDs were recovered from the house in Burdwan's Khagragarh where the blast had occurred. Two persons were killed in the incident.
An international terror network having interests in Bangladesh is suspected to have a hand in it and of the eight arrested so far in connection with the blast, most are nationals of that country.
The Bangladeshi team had already interacted with the four NIA officials, who visited Dhaka recently and handed over documents to them regarding presence of JMB in several districts of West Bengal.
NIA's information had helped the Dhaka sleuths to nab four JMB suspects, including JMB women wing chief Fatema Begum, who is also the wife of Burdwan blast prime accused Sajid.
