The CBI on Friday filed a status report on the progress of the probe in the Sohrabuddin Sheikh fake encounter case in which former Gujarat minister and Narendra Modi's close aide Amit Shah has been arrested.
Supreme court sources said that CBI officials had submitted the report in a sealed cover to the Registry.
In addition to Shah, the other main accused in the case are suspended DIG D G Vanzara and Rajkumar Pandian, both Gujarat cadre IPS officers and Dinesh M N, a Rajasthan cadre IPS officer.
Sheikh was killed in 2005 allegedly by Gujarat police with the help of Andhra Pradesh police claiming he was planning to assassinate Gujarat Chief Minister Narendra Modi.
The apex court had handed over the investigation in the case to the CBI after not being satisfied with the probe carried out by the Gujarat police's special investigation team headed by Inspector General Geeta Johri.
