CBI is part of the investigation
Explain that the CBI performs polygraph tests in most high-profile cases. This can be done earlier also. Approval of the polygraph test is taken. With this, access to the test is given to the lawyer and for this permission has to be taken from the Judicial Magistrate.
What if Riya said no?
According to the information, if Riya Chakraborty or anyone did not ask for this test while taking approval, the CBI will write this in its final report. At the same time, the things that will come out after the test cannot be kept as evidence but the CBI will be able to add them in the final report.
Therefore may have to do polygraph test
In this case, the CBI may need a lie detector test because the statements of key witnesses are not matching with each other. Neeraj, Siddharth Pithani and Samuel Miranda have been repeatedly questioned and questioned. This test can help the CBI a lot.
