CBI probes Sushant Singh Rajput Death Case: Suicide or murder? The entire nation is looking out for an answer to this question. With CBI probing this high-profile case, not just actor’s fans but his friends and family is hopeful that the lost star will soon get justice. The prime suspect Rhea Chakraborty is on the radar of not just CBI but other agencies including Enforcement Directorate (ED) and Narcotics Control Bureau (NCB) as well. The case which began as abetment to suicide took a completely new side when the involvement of banned drugs came to light through the recovered WhatsApp chats. In the wake of the investigation, not just Rhea but her brother Showik Chakraborty, Siddharth Pithani, cook Neeraj Singh, domestic assistant Keshav, manager Samuel Miranda and accountant Rajat Mewati are also being quizzed. The ‘Jalebi’ actress has been sent a summon and will have to appear before CBI on Sunday as well.
