The police say he is not an Indian national and the blast was not targeted at any political figure.
The police suspect the involvement of a Bangladeshi national and a Sri Lankan.
Both the Intelligence Bureau and police officials rule out that the train had more explosives that were being transported to some destination. The intent was to carry out a blast at a railway station and cause panic while making an announcement that a strike could occur any time.
The police say the bomb seems to have been packed in a pipe. Pipe bombs have been used regularly in Tamil Nadu. They were used in the blast before BJP leader L K Advani’s rally and in the Coimbatore blast.
