Special CBI Judge Talwant Singh directed the jail authorities to bring Kalmadi and other five officials of Organising Committee in a different van from Tihar Jail to the court for proceedings.
"Report has been received from the Deputy Commissioner of Police. Their (Kalmadi and other accused) plea for transporting in separate jail van due to security concerns is allowed," the court said.
The six accused had on July 14 moved an application expressing their apprehension of being attacked in the jail van by other undertrials.
The other arrested co-accused in the case are OC former director general V K Verma, OC former secretary general Lalit Bhanot, OC former officials M Jayachandran, Surjit Lal and ASV Prasad.
The judge had then directed the jail superintendents "to explore the possibility of transporting Kalmadi and others to the court on dates of hearing in a separate van".
The court had asked the jail authorities to apprise it with their decision by today in this regard.
Meanwhile, the court allowed V K Verma to leave on custody parole for one day on July 24 to go to Chennai to attend the last rites of his mother-in-law.
Kalmadi and others five accused are presently lodged in Tihar Jail for their alleged roles in awarding a contract for installing the TSR system to a firm, Swiss Timing Omega, at an exorbitant cost of Rs 141 crore, causing a loss of over Rs 90 crore to the exchequer.
The CBI, in its first charge sheet on May 20, has named Kalmadi and ten others including Swiss Timing and its sub-contractor A K R Constructions.
All the accused have been indicted for various offences, including those of criminal conspiracy under Section 120 (B), cheating (Section 420), forgery (Section 468 & 471) of the IPC and the Prevention of Corruption Act.
