Immediately after four low intensity blasts rocked Pune last Wednesday, Pune’s Police Commissioner, Gulabrao Pol stated that “this is definitely not a terror attack…we see it as a mischief.” As the forensic analysis of the bombs were to show days later, he couldn’t be more wrong.

Study of the two unexploded bombs has revealed that they were in a boat-shaped wooden case, a design which pushes the explosion in one direction to inflict greater damage. Ball bearings were also placed inside the bomb to cause injuries by flying shrapnel. This design has earlier been noticed in blasts elsewhere in the country. These bombs, however, were different as each of them had three detonators instead of two used earlier. The plan was to make these bombs fool-proof, and thus the terrorists also used two packs of batteries as power supply.
