M.O-5 currency notes in his pant pocket till after rinsing of his hands in sodium carbonate solution, shows that the theory put forward by the accused in his instantaneous explanation is false. Irrespective of truth or falsity of the explanation offered by the accused for possession of the tainted currency notes with him, it is for the prosecution to prove that there was demand for bribe and acceptance of bribe by the accused for doing an official favour. As per evidence of P.W-1, it was one Ramudu who is stated to have made a demand for bribe of Rs.500/-. P.W-1 did not speak to the accused making any demand for bribe. There is no other evidence to show that the accused made any demand for bribe either on the date of trap or on any other previous dates.

D.W-1 who is said to be one of the persons present in the office room of the accused at the time of thrusting of money by P.W-1 into pocket of the accused, corroborates the version stated by P.W-1 during trial. In the light of the above state of evidence of the prosecution, it cannot be said that mere recovery of the tainted cash from possession of the accused amounts to any offences for which the charges were framed against the accused.
