The man had died on Monday in custody after his 18-year-old daughter had accused a BJP MLA, his brother and his aides of raping her. The bench passed the order on a letter written by senior advocate Gopal Swaroop Chaturvedi demanding a court-monitored investigation of the incident and treated it as a PIL.
Earlier, the state government informed the bench that the CBI had taken over the investigation of Unnao rape case.
The ruling Bharatiya Janata Party government in Uttar Pradesh handed over the Unnao rape case to the central agency after coming under attack from its political rivals for allegedly shielding Sengar.
The agency, which was referred the case Thursday, sprung into action immediately by re-registering the UP police FIRs and brought the MLA to its Lucknow office at around 5 am for questioning, officials said, adding that a team of officials would visit the scene of crime and question jail officials, police officials and family members of the MLA.
Acting on this information, the court directed the CBI to investigate the case strictly and consider the filing of an application for cancellation of bail granted to other accused in the rape case.More news: Britain attacks Syria with cruise missiles to deter more chemical attacks

In spite of the SIT report, you are repeating that we can only take any action after further investigation, if this is the conduct of the police in state, whom will a victim approach to register a complaint. The FIR has been registered under Sections 376 (rape), 366 (kidnapping, abducting or inducing a woman to compel her marriage), 363 (kidnapping) and 506 (criminal intimidation) at the Maksi police station.
The BJP MLA has been charged under the stringent POCSO Act and sections of the Indian Penal Code or IPC dealing with rape.
