Pune Police have asked the postal department to be careful and alert while handling \u2018suspicious looking parcels\u2019 as they can be stopped and investigated at the place of their origin. Parcels like the ones sent at the Film and Television Institute of India (FTII) and Pune University\u2019s journalism department could have even exploded as they contained live detonators, police said. It\u2019s been four days since FTII received an India Post parcel containing a live detonator, another \u2018explosive like substance\u2019 and a threat letter. Two days later, the journalism department of SPPU received an identical package threatening the institute administration and others of dire consequences if they invited Jawaharlal Nehru University students\u2019 union president Kanhaiya Kumar. [related-post] \u201cWe are closely working with the postal department and their senior officials are helping us find the source of the parcels. So far, we have not been able to locate the place or the post office from where these parcels originated,\u201d said Sudhir Hiremath, Deputy Commissioner of Police, Pune. We have inspected CCTV footage of major post offices in the city. It\u2019s a difficult task because each post office has at least six deposit boxes, and so the mischief maker could have used any of these, especially one which is not covered by any CCTV camera,\u201d Hiremath added. He further said that all police officials have been instructed to remain alert and flag suspicious looking parcels. \u201cThere are some signs that can show that there\u2019s something amiss in a parcel. For example, the FTII parcel which would require only one Rs 10 stamp, was stamped with four. The miscreant could have done it because the seal on the stamps has much less readability than plain paper. If not carefully handled, the detonators in these parcels could have exploded. So we have asked postal employees to be careful,\u201d Hiremath said. Pune Police Commissioner Rashmi Shukla reiterated that there is a strong possibility that the parcel originated locally. \u201cPrima facie it looks like it originated locally. Several teams of Pune police are investigating it,\u201d she said.
