A division bench of justices A S Oka and A A Sayed earlier this week directed the government to file the report in a sealed cover on the status of its investigation against Singh.
The court directed that the report should be submitted within two weeks.
The bench was hearing a petition filed by activist Tulsidas Nair seeking a CBI probe against Singh, claiming the state machinery has not done proper investigation in the case.
The direction was passed during the hearing of a public interest litigation filed by another activist Sanjay Tiwari.
