A bench of Justices J S Khehar and Arun Misra issued notice to the government and CBI on a plea filed by former bureaucrat EAS Sarma, who sought setting up of a Special Investigation Team (SIT) comprising officers with impeccable integrity to probe the incident.
The plea also sought prosecution of those allegedly involved in the suicide of Bansal and his family.
Bansal, a former Director General of Corporate Affairs, was facing a CBI probe in a corruption case, and his son allegedly committed suicide at their East Delhi residence on September 27.
The two had left separate suicide notes, saying the "CBI raid" caused them "great humiliation" and they did not want to live after that.
They had however held nobody responsible for their death. Bansal, an additional secretary-rank officer in the Ministry of Corporate Affairs, was arrested by CBI on July 16 for allegedly accepting bribe from a prominent pharmaceutical company.
CBI had carried out searches at eight locations in connection with the case during which the agency had claimed to have made cash recoveries. He was later arrested but released on bail.
