Sushant Singh Rajput case: Police to summon actor's sister and cook again?

As per reports, they want to know more details of the days leading up to the actor's death.

According to a report in The Times of India, late actor Sushant Singh Rajput's cook Neeraj and his sister Mitu could be questioned again by Mumbai police in the ongoing investigation into the actor's death.
Neeraj was reportedly one of the first people to be questioned by police. This time the police will interrogate him as to the happenings between June 11 and 14, the date of Sushant's death. As per reports, they want to know the actor's schedule of activities for these days, as well as what meals he had and other details.
Neeraj was earlier questioned for almost six hours by police.
Sushant's sister Mitu will also be interrogated as police want details of her talk with the actor three months ago and whether he revealed any personal details about his rumoured relationship with actress Rhea Chakraborty with whom he reportedly had a fight in the days prior to his death.
Although a post-mortem declared Sushant's death as a suicide, fans are demanding a CBI enquiry into the matter.
