The apex court said Kumar will appear before the Central Bureau of Investigation (CBI) for investigation at Shillong in Meghalaya. The apex court also said no coercive steps, including the arrest of the Kolkata Police chief, will take place during the course of investigation.

A bench headed by Chief Justice of India (CJI) Ranjan Gogoi also issued a notice to Kumar and sought his response before February 20, the next date of hearing on the allegations by the CBI that he was tampering with electronic evidence and that the SIT headed by him provided the agency with doctored materials.

The bench also comprising justices Deepak Gupta and Sanjeev Khanna said on consideration of replies of the chief secretary, the DGP and the Kolkata police commissioner, the court might prefer the personal appearance of these three authorities on February 20.

The bench said the apex court's secretary general will inform them on February 19 whether they are required to be present before the apex court on February 20.
