Kumar arrived here this morning and left for Burdwan where he met NIA investigators and assessed the progress in the probe into the blast at Khagragarh in Burdwan town on October 2 that claimed the lives of two suspected terrorists of Jamaat-ul-Mujahideen Bangladesh.
Three persons, including two women – one of them the widow of a suspected terrorist who died in the blast, had been interrogated by NIA.
