Controversial CDs purportedly containing the voice of Himachal Pradesh Chief Minister Prem Kumar Dhumal ordering tapping of Union Minister Virbhadra Singh's telephone have surfaced in Shimla. But Mr Dhumal rubbished their contents and ordered a CID probe into the issue. <br/><br/>The probe will be carried out by Additional Director General of Police, CID, I D Bhandari, official sources said. No time frame has been fixed for completion of the task, but the CID has been asked to submit its report at the earliest. <br/><br/>A packet containing two audio CDs and one video CD was sent to some newspaper offices in Shimla last night. In one audio CD, Mr Dhumal, who belongs to BJP, is purportedly giving a go ahead to Director General of Police (State Vigilance and Anti-Corruption Bureau) D S Manhas to tap phones of his Congress rival Virbhadra Singh and his wife Pratibha Singh. Mr Singh, who served as Chief Minister five times before becoming a union minister, had in the past alleged that his telephones were being tapped by the state authorities.
