New Delhi: The investigation of NRHM scam and the murder of CMOs V K Arya and B P Singh in Uttar Pradesh by the CBI would be delayed as the Ministry of Personnel has not given the notification to the premier agency yet for probing the matter.

According to a senior CBI official, “As soon as we receive the copy of the notification, we will register an FIR and initiate the investigation.”

According to the norms, the state and the Central governments are required to release separate notifications for the CBI probe. While the state government has already released a notification last week for CBI investigation in the case, the Ministry of Personnel is yet to do the same.

Meanwhile, the CBI is engrossed in the interrogation of jail officials, security guards and prisoners regarding Dr Y S Sachan death case. The sources have revealed that the CBI is involved in preparations to interrogate detained CMO Dr A K Shukla.
