Delhi Police
The IB, CBI and the Delhi Police are all trying to prove that they are the best at apprehending criminals. The PM decides to give them a test. He releases a rabbit into a forest and each of them has to catch.

The IB goes in. They place animal informants throughout the forest. They question all plant and mineral witnesses. After three months of extensive investigations they conclude that rabbits do not exist.

The CBI goes in. After two weeks with no leads they burn the forest, killing everything in it, including the rabbit, and they make no apologies. The rabbit had it coming.

The Delhi Police goes in. They come out two hours later with a badly beaten bear. The bear is yelling: "Okay! Okay! I'm a rabbit! I'm a rabbit!
