NEW DELHI, July 10 -- The Central Bureau of Investigation (CBI) on Thursday informed a Delhi court that it did not find evidence to prosecute any senior civic official for criminal negligence or lapse for allowing a library to be run at the basement of Rau's IAS Coaching Centre, where three students drowned in 2024. In a closure report filed before Special Judge Dinesh Bhatt of Rouse Avenue Courts on Wednesday, the agency submitted that it had investigated the role of two senior Municipal Corporation of Delhi (MCD) officials, then deputy commissioner of Karol Bagh Zone, Kumar Abhishek, and then superintending engineer, Ajay Nagpal. The CBI said that both the officials were unaware of the misuse of the basement. "A final report in the form of closure is being filed regarding court's direction on the aspect of possible dereliction/corrupt practices by senior MCD officials. No evidence has come on record to prosecute any other official," the CBI said in the report, a copy of which was accessed by HT. The report stated that a joint engineer (JE) of MCD, Arnav Kumar Dutta, had already been chargesheeted in the case. "He despite knowing the fact that the basement was being used for the purpose of commercial activity deliberately did not report the same to his higher authorities, even after conducting inspection of the said premises multiple times," the report read. On July 27, 2024, heavy rains flooded the basement of Rau's IAS Coaching Centre in Old Rajendra Nagar, where Nevin Dalvin, Tanya Soni, and Shreya Yadav, all UPSC aspirants, drowned. The basement was being illegally used as a library despite being sanctioned only for parking and storage. The CBI said that it was Dutta's actions which contributed to the continued and unauthorised use of the basement and amounted to improper discharge of duty and dereliction on his part. It added there was no cogent evidence to prosecute any other MCD official. The court has listed the closure report for consideration on July 28....
