"Out of 17 accused, 16 have been arrested and one is absconding, attempts to arrest whom are going on. But the CBI is constantly under pressure because of the involvement of high-profile persons and the witnesses are also being threatened thereby affecting the investigation," Singh said in a statement before the court.
Some key witnesses have also gone missing due to this pressure, he added.
However, the division bench comprising Justice Govind Mathur and Justice KC Joshi asked him to submit an affidavit in the court instead of being vocal in his statements and problems and deferred the hearing till February 27.
Before this, the Additional Advocate General Anand Purohit pleaded the court to declare the petition in fructuous.
But in absence of the charge-sheet and written submission confirming that corpus is no more, the court refused to grant the plea of the AAG.
The agency had told the court in the previous hearing last month that midwife Bhanwari Devi is no more and requested the court to quash the habeas corpus petition filed by Amarchand.
The court, however, refused to quash the petition and asked CBI to produce the final report on February 21.
