The Mumbai Police, in a 20 page affidavit filed in the Supreme Court, denied that sending IPS officer Vinay Tiwari into quarantine was aimed at obstructing the investigation by the Bihar Police. This was in the case registered by late Bollywood actor Sushant Singh Rajput's father in Patna. It also submitted that pending the present proceedings, the Central Bureau of Investigation ought not to have gone ahead to register a case and constitute a team for conducting the investigation.
