New Delhi, July 31 : The Income Tax Department has unearthed fresh evidence in the VVIP choppers scam case after raiding a Hyderabad-based group which had purported dealings with Dubai-based accused in the case, Rajiv Saxena, the CBDT said on Wednesday. It said in a statement that tax sleuths searched on July 24 the premises of a business group engaged in conducting seismic data analysis and four undisclosed foreign bank accounts, three un-reported companies based in tax havens, and unexplained cash of Rs 45 lakh and jewellery worth Rs 3.1 crore were recovered.
