Mumbai, May 4 -- The Central Bureau of Investigation (CBI) booked an official at the Regional Transport Office (RTO) of Silvassa, Union Territory of Dadra and Nagar Haveli and Daman and Diu, in a bribery case on April 9, agency officials said on Sunday. The case was registered based on a complaint filed by a Mumbai-based transporter, who alleged that the accused official and his aide sought a bribe to register a new vehicle at the Silvassa RTO . The complaint alleged that inspector B Pawar, the accused official, solicited a bribe on April 1, when the complainant approached him to register his newly purchased vehicle. The complainant stated that Pawar instructed him to meet his aide, a certain M Kokani, who runs a motor-driving school in Silvassa. Kokani allegedly reiterated the bribe demand on behalf of Pawar, CBI officials said. The complainant further stated that the accused duo allegedly demanded a bribe equivalent to 1 per cent of the vehicle's purchase price, which was Rs.11.95 lakh. After the transporter, who runs school vehicle services, alerted the CBI, the agency discreetly verified the allegations on April 9 in the presence of independent witnesses. During the verification, Kokani allegedly confirmed Pawar's bribe demand to process the registration at the RTO in Silvassa, but agreed to accept Rs.10,000 after negotiation, the agency officials said. After the confirmation, the CBI registered a case against the duo under relevant sections of the BNS and Prevention of Corruption Act, relating to bribing a public servant and using corrupt or illegal means to influence a public servant....
