At 6.30 am on Thursday morning a team of the National Bomb Data Centre (NBDC) led by a lieutenant colonel visited the blast spot outside McDonald's restaurant on Jangli Maharaj road.
The team collected samples of the explosive that that had gone off outside the restaurant. Preliminary investigations reveal that the explosives contained ammonia and a sticky substance which was detonated using a detonator.
Soon after the NBDC team left, a team of police officials collected the bicycles and dustbins in an investigation van. The bicycles and dustbins would be part of the material evidence, said a police official.
The entire Jangli Maharaj street, a plush locality in Pune, which was cordoned off till morning was later opened for traffic.
A police officer at the site, requesting anonymity said, "The intensity of the blast was so low that it did not even pierce the dustbin in which the explosive was kept. The basket on the bicycles had a minor aberration. The bicycles did not even fall to the ground."
Pune police suspects the role of at least three persons in planting the bombs outside McDonald's restaurant, Bal Gandharva theatre, Dena Bank and City shoes shop. One person identified as Dayanand Patil was injured in the blasts.
