The Central Bureau of Investigation (CBI) on Wednesday slammed the Mumbai Police for registering an FIR against late Bollywood actor Sushant Singh Rajput's sisters on the complaint of Rhea Chakraborty, saying it is "vitiated" and "bad in law".

The CBI made the submissions in the Bombay High Court while opposing the second FIR filed by Mumbai Police on the complaints of Rhea related to the death of Sushant.
