The Patiala Deputy Commissioner has ordered a high-level probe to ascertain if “a criminal case can be lodged” against former Additional DGP Gurcharan Singh Bhullar for allegedly “conniving with three patwaris” to sell his property at Stadium Road in Patiala. The three patwaris who connived to give false clearance to the property by “tampering with official files to give clearance to the property documents in revenue files” stand suspended and are facing a departmental probe.
