The Centre may issue a notification to this effect soon asking the NIA to carry out the probe into the incident that took place on December 28 when suspected militants had wrapped the improvised explosive device in a plastic bag and placed it in a bushy plant.
The restaurant is close to the fashionable Brigade Road and MG Road, dotted with bars and restaurants with teeming crowd on weekends.
Initial leads suggested the role of banned SIMI behind the attack and NIA had provided all assistance to the state police during the probe.
