He said the man got off the train at 7.08 a.m. The two bombs went off in succession at around 7.15 a.m. According to Agarwal the man was not seen getting on the train at the Chennai Central station but was only seen getting down and running away.
The police officer said the investigating team is also checking the camera footage at all other stations between Bangalore and Chennai Central stations. According to him, there is no evidence to suggest that the bombs could have been planted at the Chennai station. He said the forensic science wing has recovered some pieces of cloth and metallic parts that indicate it to be a time bomb variety. The train was scheduled to reach Chennai Central at 5.40 a.m. but was running late by 90 minutes and entered the station at 7.05 a.m. Ruling out the connection of the arrested Sri Lankan Mohammed Zakir Hussain with the blasts, he said the investigation team is pursuing some leads in Bangalore.
