Jalandhar: Enforcement Directorate Assistant Director Niranjan Singh, who was investigating synthetic drug racket case and also summoned Punjab revenue minister Bikram Singh Majithia has been transferred to Kolkata. In the last couple of days local ED officials had reported that they were being bugged and Punjab CID sleuths. Interestingly some phone numbers from which the calls were made by the CID sleuths to the ED officials were also brought into the public domain by the latter, which created embarrassing situation for the Punjab government and its intelligence wing.
