Considering that it had taken place near a place once a beehive of naxal activity and where top naxal leader Siva was killed in an encounter with the police a few years back, the naxals would have planted the detonators at the track between Samalpatti and Thasampatti, which exploded when the Patna-Ernakulam Express train passed through, the police suspected.
However, the passengers of the train had a miraculous escape.
Though police said the gelatine sticks used at the railway track near Krishnagiri might have been brought for stone quarry purpose, they also suspect that the blast would have been done by the naxalites following a series of setback suffered by them.
Two days ago, six Tamil terrorists were arrested in Cuddalore.
Also, 11 people belonging to Tamil Nadu Liberation Army were sentenced to ten years imprisonment in connection with the 1994 bomb attack at Kullanchavadi police station in which a policeman was killed.
The Madurai High Court also ordered 10 years imprisonment for Punithan, a naxalite involved in Kodaikanal blast. Following the verdict, a group decided to raise funds in Chennai, so that they could appeal to the Supreme Court. However, police refused to give them permission to conduct the meeting at a marriage hall in the city.
Also, police refused to give permission to Gaddar, a popular ballad singer and a sympathiser of Naxalite to participate in a conference in Chennai. The meet was organised to extend support for the arrested women naxalites near Oothangarai after the encounter killing of Siva.
Following a series of setbacks, the irritated naxalites would have planted the gelatine blasts near the railway track, police said.
