Accepting the third investigation report submitted by the CBI in a sealed cover on Wednesday,the Bombay High Court said it was time to question some vital persons in the Adarsh Society scam. After going through the report submitted by Additional Solicitor General D J Khambata,the court said although the CBI investigation was going in the right direction,the time has come to question some vital persons. Khambata informed the court that the CBI has so far examined nearly 70 witnesses. Justice Ranjana Desai and Justice R V More,however,felt that the investigating agency must now come to a conclusion. The court was informed that the CBI will require at least two to three months to complete the probe. The court was hearing two PILs filed by social activists Simpreet Singh and Pravin Wategaonkar. The HC was also informed that more documents in the Adarsh scam had gone missing. Khambata,however,said they have not been formally informed about any more missing documents. Speed up the investigation otherwise its purpose will be lost, Justice Desai told the CBI. Singhs advocate Ashish Mehta told the court that of the three former Maharashtra chief ministers named in his clients petition,two have already filed their affidavits before the Adarsh inquiry commission,but havent been interrogated by the CBI yet. The court asked the CBI to submit another investigation report in four weeks. The case has been adjourned till July 20 when the Income Tax department is likely to apprise the court of its findings in the scam.
