Chennai: A Special Investigation Team would probe the twin bomb blasts that rocked the Bangalore-Guwahati Express today, leaving a woman dead and 11 others injured.
Tamil Nadu DGP K Ramanujam said after the Railway Police registers the case into the explosion, the investigation will be taken up by a Special Investigation Team.
"It is not a major blast. It is suspected that Chennai could not have been target of those who were behind the blast because the train was running late. Some other location could have been the target", Ramanujam said.
He said police have no immediate information on who was responsible for the explosion in which 11 people were injured.
"It is premature to say what kind of device was used is the blast. Damage to the train is not heavy," he added.
Ramanujam, who inspected the damaged S4 and S5 coaches of the train, said police are thoroughly searching the train and forensic experts and bomb disposal squads have been pressed into service, besides sniffer dogs.
"City police, Railway Police, forensic experts and bomb disposal squads have been searching the coaches thoroughly. The coaches of other trains are also being checked", he said.
City Police Commissioner J K Tripathy, who also visited the scene of blast, said police were investigating the blast.
"Any speculation on who did it...How it occurred is premature. We have no information as of now", he told reporters.
DGP (Elections) Anoop Jaiswal said, "We are picking up clues and any speculation on this is too premature".
Jaiswal said nobody has been arrested in connection with the blasts.
However, police sources said a person has been detained and is being questioned.
