Chennai: The Tamil Nadu CB-CID on Friday indicated that the twin blasts in Chennai might have some connection with the Patna serial blasts as there was some similarity in the explosives used in both the incidents.
Timer device was used in the twin blasts that rocked the Bangalore-Guwahati Express at Chennai Central Railway Station, confirmed Tamil Nadu CB-CID on Friday.
The device was timed to go off in Andhra Pradesh, said Mahesh Kumar Agarwal, IG, CB-CID, Tamil Nadu. "Train was scheduled to reach at 5.40 am, there was a 90 minute delay, train would have reached Andhra at the time explosion," he told reporters in Chennai.
But as the BJP was claiming, the blasts were not targeted at its prime ministerial nominee Narendra Modi. "No information on any intended target, we are verifying passenger details," said the CB-CID.
Agarwal also said that the probe team had not yet established any link with the arrested Sri Lankan national, Zakir Hussain, who is also allegedly the agent of an ISI operative.
CCTV footage obtained from the railway station is being scrutinised and the movement of a person in particular was being monitored, added Agarwal.
