Justice SR Krishna Kumar directed the police "not to file final report without leave of the court" after the counsel for RCB and DNA told the court they had been cooperating with the ongoing investigation by the police into the three suo motu First Information Reports (FIRs) registered against them and the Karnataka State Cricket Association (KSCA) following the stampede.
