The Mumbai police is also investigating the matter.
"Thus, now two states are investigating in the matter arising from the same sad event of the unnatural death of Sushant Singh Rajput. Therefore, it is in the larger interest of justice that there should be a single investigation...," Swamy said.
This is the Rajya Sabha MP's second letter to the prime minister over the matter.
He said he had enclosed with the letter a tabulation, giving "24 reasons why Sushant Singh Rajput's mysterious death is actually a murder, not a suicide".
Swamy claimed that there are "enough multi-dimensional issues connected with the untimely death" of the actor, which require a "joint investigation by CBI with NIA and ED".
He alleged that terror links of Rajput's "opponents" and money laundering appear to be factors in his death.
"I think in the larger national interest, your intervention is required and I request you to take necessary steps to ensure that a comprehensive investigation as suggested above is carried out in the larger national -- social, political and security interests," Swamy wrote.
