Homicide by improvised explosive device made out of firecrackers.

Explosion is a phenomenon resulting from a sudden release of energy dissipated by: (1) blast wave; (2) translocation of objects; and (3) generation of heat. There are different types of explosive devices varying from sophisticated military bombs to simple firecrackers. These are made from various kinds of explosive materials. Sophisticated bombs are used in war and military operations to kill one's enemies, while simple firecrackers are meant for expressing joy and celebration. Here, the author reports an unusual case of homicide by the manufacture of an improvised explosive device from simple firecrackers. In India, these firecrackers are widely and freely available all over the country. The case highlights the fatal hazard resulting from easy access to these potentially dangerous devices, apart from the environmental pollution produced by their large scale use at the time of festivals in this country.
