The CBI today released from its custody Rahul Anand, son of prime accused in shelter home sex scandal Brajesh Thakur. Anand was picked up from his residence last night by a CBI team, which had spent close to 12 hours conducting raids on the premises of the now-sealed shelter home and the office of a Hindi daily "Pratah Kamal", owned by Thakur's family. He returned to his residence early this morning after several hours of CBI grilling. The CBI is understood to have been looking at various angles, which include sexual abuse of inmates at the Muzaffarpur shelter home, misuse of public funds allocated to an NGO controlled by Thakur, and the alleged links of high-profile people with the prime accused. The NGO, Seva Sankalp Evam Vikas Samiti, was blacklisted in June, soon after an FIR was lodged by police in the case, subsequent to the exposure of details of sexual abuse of inmates in a social audit report. The audit report by Tata Institute of Social Sciences gave explicit information on the physical exploitation of minor girls at the shelter home. In a raid conducted at the Muzaffarpur jail yesterday, which led to the recovery of several banned items, a piece of paper was seized from Thakur with names and mobile numbers of 40 people. District Magistrate Mohd Sohail said the paper has been handed over to the Mithanpura police station for investigation and a complaint may be lodged in the matter if it was found that Thakur had been making calls from the jail to any of the numbers mentioned in it. In a related development, an FIR has been lodged at the Mahila Thana in Muzaffarpur town of the district against Shibha Kumari, the wife of a district child protection officer Ravi Roshan, who is among the 10 persons arrested so far in connection with the scandal. Kumari recently caused a flutter by alleging that the husband of former social welfare department minister Manju Verma was a regular visitor at the shelter home and that Roshan was being made a scapegoat to shield some "big fish". Verma had resigned from her post last week while maintaining that her husband was innocent. She threatened to file a defamation suit against Kumari. The FIR was registered following a direction from the Supreme Court, which taking suo motu cognizance of the case, expressed displeasure that Kumari, in her outbursts in public and on social media, made public the identity of some of the victims in violation of law.
