Just days after a preliminary probe by Uttarakhand health department suggested that many of the four lakh Covid test results issued during the Kumbh festival in Haridwar were fake, a detailed investigation — running into 1,600 pages and accessed by TOI — has found that at least 1 lakh test reports were forged by a private agency. The 200 sample collectors employed by the agency too turned out to be students and data entry operators in Rajasthan, who had never been to Haridwar. Haridwar DM C Ravishankar has said payment to all agencies have been put on hold until further notice.
