"Azad Nagar police helped the NIA team to arrest a person. The police verification of the tenant was not done as the landlord did not inform the police about it," Additional Director General of Police Varun Kapoor told mediapersons here.
The police sources said that Sheikh has been working as a labourer in other cities for the last two years.
Zahirul Sheikh is an active member of Jamaat-ul-Mujahideen Bangladesh (JMB) and a close aide of Rezaul Karim, another suspect arrested for transporting explosives to various places in Burdwan. Sheikh is a key accused in the 2104 Burdwan blast in which two suspected Indian Mujahideen terrorists also died. Sheikh participated in training camps and is trained in making bombs.
It is being feared that Sheikh was in Indore to carry out some major operation. But this has not been confirmed by NIA or the police.
