The NIA, which is probing the Oct 2 blast in West Bengal's Burdwan in which terror links are suspected, Thursday seized a sack full of IEDs from a house in the area.
"A NIA team accompanied by the Burdwan police conducted search of a house of one important person linked with the incident located in Burdwan wherein a sack full of IEDs concealed in a room have been recovered," the agency said.
The National Investigation Agency said it was pursuing the absconding man, said to be a key accused, from whose house the improvised explosive devices (IEDs) were recovered.
A National Security Guard (NSG) team was employed to dispose off the seized explosive.
A NIA team continued combing the areas surrounding a madarsa in Simulia near the explosion site. The two women, who are now in NIA custody, were radicalised in violent Jihadi ideology at the madarsa.
The blast occurred in a house in Khagragarh area killing two suspected Jamaat-ul-Mujahideen militants and injuring another. Several people including the two women have been arrested in this connection.
Besides arresting six people in Bengal and six others from Assam in connection with the incident, NIA sleuths have also interrogated three people in Chennai.
