Pune bomb was kept in backpack: Chidambaram

After an early morning visit, Chidambaram told reporters that the terrorist who brought the bomb to the German bakery on Saturday evening may have posed as a customer.

"The bomb was apparently planted in a backpack and left there. The person apparently came there as a customer, unlike the usual gun-wielding terror attacks," he said. The deafening blast also injured nearly 60 people, some of them critically.

It was the worst terror attack in India after November 2008 when a group of Pakistani terrorists went on a killing spree in Mumbai leaving 166 Indians and foreigners dead.
