The CBI is questioning actor Rhea Chakraborty for the second day in the Sushant Singh Rajput death case. She was grilled by the CBI on Friday for over 10 hours. Media reports quoting sources said that Rhea was asked why did she leave Sushant's house on June and did she have a fight with him before leaving. The actor, who was living with Sushant, was also asked if she had any communication with him between June 8 and 14, when Sushant was found hanging in his house. Rhea was also asked about Sushant's mental health and the treatment he was taking. The CBI also interrogated Rhea's brother Showik separately. Sushant's friend Siddharth Pithani, cook Neeraj Singh and another staff member Keshav Bachner are also being questioned at the DRDO guest house where CBI team probing the case is staying.
