They are perhaps the last surviving pack of bandits who move about on horseback. But, apart from that, they have very little in common with that Hindi-film stereotype - the benevolent, towering Robin Hood figure of the Chambal ravines. On the contrary, they are a ruthless, bloodthirsty horde of criminals controlled by the contractor-politician-caste mafia of Bihar. A mafia whose tentacles extend from the unapproachable, back-of-the-beyond diyara (riverine) areas to the Patna Vidhan Sabha. Backed by this nexus, these gangs of criminals find it easy to ride in, swoop down on their prey and indulge in a bout of murder and plunder. After which they simply melt into the hilly terrain beyond the Kiul river in the Lakhisarai, Begusarai and Munger districts.
