The Narcotics Control Bureau, which is looking into the allegations of drug use by late Bollywood actor Sushant Singh Rajput and his actor-girlfriend Rhea Chakraborty, questioned her for nearly six hours on Sunday. Rhea was allowed to leave the NCB office in Mumbai at around 6.15 pm. The NCB said ‘due to her late arrival, the investigation has not been completed and it will summon her again on Monday’. On Sunday, Rhea’s advocate Satish Maneshinde said that she is ready for an arrest as this is a ‘witch hunt’. The NCB also produced Sushant's domestic help Dipesh Sawant before a magistrate court which extended his custody till September 9.
