The victim, Yuvaraj of Maduravoyal, reportedly gave Rs 8 lakh to one Karthik alias Siva (38) of Tiruverkadu, who is as a part-time driver, as the latter wanted to start a business. However, when he demanded the money back, Siva sent his friend, M Jaishankar alias Vijayakumar (46) of Otteri, to threaten him. Jaishankar allegedly told Yuvaraj that he is police personnel attached to the Gangsters team of CCB and warned him to stay away from Siva.
