"We have filed an interim report on the photograph that appeared recently in sections of media to a TADA court. An Additional Commissioner level officer had conducted the inquiry," said CBI Special Prosecutor Deepak Salvi.
Salvi also sought four weeks' time to further inquire into the matter.
Special TADA judge G A Sanap took the report (presented in a sealed cover) on record and granted additional time.

Salem, speaking to reporters in the court premises later, had said the report was a baseless "rumour".
