card. Accordingly, on the very same day, at about 9.00 p.m., P.W.1 met the accused with the required documents, and after verifying the same, the accused demanded Rs.300/- as illegal gratification for processing the approval for grant of no objection certificate. Pursuant to the said demand, the accused received the documents as well as a sum of Rs.50/- and also obtained the signature of P.W.1. The accused asked P.W.1 to pay the balance sum of Rs.250/- as condition for granting the necessary approval towards processing the passport application. Thereafter, on 19.08.2009 at about 9.30 a.m., P.W.1 along with his friend, P.W.12, met the accused at Kabisthalam Police Station and again the accused reiterated his earlier demand. As P.W.1 was not willing to pay the amount and accede to the guiles of the accused in demanding illegal gratification for performing his official duties and, therefore, P.W.1 approached P.W.13, the officer attached with the Vigilance & Anti-Corruption Department and gave a complaint, Ex.P-2. After recording the statement from P.W.1., P.W.13 registered a case in Cr. No.8 of 2009 for the offences stated above. P.W.13, thereafter, requested the assistance of official witnesses and, accordingly, P.W.2 the Junior Engineer, attached with the office of the Electricity Board and one other person, viz., Sivanesan, Assistant, employed in the office of the Tamil Nadu Housing Board, appeared before P.W.13. P.W.2 and the said Sivanesan were provided with the copy of the complaint given by P.W.1, which was read over by them and they ascertained the truth and veracity of the same from P.W.1, who was also present at the office of P.W.13 at that time. In furtherance to the same, P.W.1 produced five numbers of Rs.50/- notes, which was counted by Sivanesan. P.W.2 and Sivanesan were allowed to interact with P.W.1 for ascertaining the details. P.W.13 after explaining the details of the trap operation to all the persons gathered in his office, proceeded to coat the five numbers of fifty rupee notes with the chemical Phenolphthalein, after noting the numbers on the currency notes. After coating the currencies with Phenolphthalein and experimenting as to its proper functioning, P.W.13, along with P.W.1, the defacto complainant, P.W.2 and other members of his team, proceeded to Kabisthalam Police Station, where the accused officer was working. P.W.13, instructed P.W.2 to watch the unfolding of the sequence of events that are to take place on P.W.1 handing over the amount to the accused.
