The father of the RG Kar Medical College rape and murder victim on Thursday questioned the CBI's investigation, alleging it's a cover-up and the agency is not doing its job properly. Speaking to ANI, he claimed that the High Court made a mistake by handing the case over to the CBI, saying they won't admit their involvement in the crime. The grieving father said, "The High Court can't be this foolish as to hear this case in a single day and hand it over to a fool like the CBI. We are deeply saddened by this."

The victim's family is seeking custodial interrogation of police officers and doctors, including Sudipto Roy, who they believe are involved in the conspiracy. The CBI had arrested Sanjay Roy, who was later convicted and sentenced to life imprisonment. However, the victim's family believes there's a larger conspiracy and wants further investigation.
