Mumbai, April 7 -- The Juhu police have arrested a 36-year-old man for allegedly impersonating a Brihanmumbai Municipal Corporation official and attempting to extort Rs.15,000 from a resident. The accused, identified as Kevan Kiran Joshi, is a former cleanup marshal with the civic body, police said. According to the complaint, Ramprasad Ganeshprasad Sharma, 59, a domestic help employed at the residence of musician Arvind Nanakchand Mehra, said interior renovation work had been underway at the flat and the debris from the work had been kept within the building premises with the society's permission. Over the past four days, Joshi allegedly approached Sharma, claiming to be a BMC official and warned that dumping debris in the compound could attract a fine of Rs.1.60 lakh but offered to "settle" the matter for Rs.15,000. On Monday, Joshi returned to the spot and reiterated that he would initiate action. Sharma grew suspicious and alerted the police. During questioning, Joshi admitted that he was not on duty and had previously worked as a cleanup marshal, a position that has since been discontinued. Police subsequently held Joshi....
