The ministry in its letter dated January 7 asked All India Institute of Medical Sciences (AIIMS) to conduct its own probe.
"The matter has been considered in the ministry. The institute is requested to investigate the matter appropriately. This issues with the approval of Health and Family Welfare Ministry," it said in its letter to the Director of AIIMS.
Health Ministry sources said that this was an internal matter of the AIIMS and there is no possibility of referring the matter to the IB.
The media organisation had published several reports on alleged irregularities at AIIMS based on that information.
