NIA chief Sharad Kumar Friday arrived in West Bengal's Burdwan district to take stock of the investigation into the Oct 2 blast in which militant outfit Jamaat-ul-Mujahideen Bangladesh is suspected to have been involved.
The blast of an improvised explosive device (IED) in a rented house in Khagragarh killed two suspected militants and injured another.
Six people, including two women, have been arrested for the blast which is being probed by the National Investigation Agency (NIA) following a directive by the union home ministry.
NIA Director General Sharad Kumar, accompanied by Inspector General of Police Sanjeev Kumar Singh and Superintendent of Police Vikram Kharate, visited the house in which the blast occurred.
He is also slated to visit the Simulia madarsa and then go to Beldanga in Murshidabad district where one of the killed militants, Shakil Gazi, had a rented accommodation.
Kumar will later hold a meeting with the NIA probe team in Kolkata.
