The CBI is currently investigating Sushant Singh's death. The probe will reveal the reason behind his death.
Some of his associates, friends, and persons known to him have expressed doubt over the situation in which the body was found. They have speculated that the actor may have been murdered and did not die by suicide. The ambulance attendant said that he heard doctors speaking after the autopsy of Sushant that it was a murder. But Forensic experts have said there is no foul play, and it was a clear case of suicide. Further, Mumbai Police Commissioner Param Bir Singh said that Sushant Singh had bipolar disorder and sought treatment for it.
The Central Bureau of Investigation (CBI) has taken over the case after much deliberation, and the investigation is ongoing. As of now, there is no evidence to confirm whether Sushant was murdered or died by suicide.
