A team of National Investigation Agency (NIA) on Wednesday reached Bhopal to probe the blast in a train, suspected to be a terror attack.
The blast occurred near the Jabri railway station under Shajapur district, about 60 km from Bhopal.
NIA officials would interact with the Madhya Pradesh police personnel and verify leads available with them to ascertain whether the explosion was a terror attack, official sources said.
Madhya Pradesh Home Minister Bhupendra Singh on Tuesday said the initial investigation suggested that the blast was a terror attack and investigation was underway to unravel the conspiracy behind the incident.
Ten people were injured, three of them seriously, in the blast on the Bhopal-Ujjain passenger train.
Madhya Pradesh Inspector General (Intelligence) Makrand Deoskar had said the blast was carried out “by planting an improvised explosive device (IED)”.
