Some more suspects in the twin bomb blasts in the Kaziranga Express have been identified, Tamil Nadu Police said today claiming it has got "positive" clues on the explosions that killed a woman passenger and left 14 others injured.
A careful perusal of CCTV footages at the Chennai Central Station, Bangalore City Railway station and those between Bangalore and Chennai has led the CB-CID police, probing the explosion to zero in on some "positive" leads, a senior official involved in the investigation said here.
He said "some more suspects have been identified" but declined to elaborate, saying it would hamper investigations.
The official said a police team sent to Guwahati was camping there and questioning some of the passengers who travelled by the train looking for more clues that could help them track down the perpetrators of the blast.
The CB-CID police have sought the help of experts to confirm whether a suspect who boarded the Bangalore-Guwahati express at Bangalore and who was masking his face with handkerchief, was the same person who was seen hurriedly alighting at Chennai, the official said.
Police are also looking at the possibility of the blasts being the handiwork of Indian Mujahideen or some sleeper cells, he said.
A police team is continuing investigation at Bangalore.
The CB-CID has also deputed a team to Patna against the backdrop of investigations indicating that explosions there hours before Narendra Modi's "Hunkar" rally, was similar to that of Chennai blast.
