Three witnesses - Sanjay Dewan, Narain and Bajrangi linked to the Sunanda Pushkar murder case have said they are ready to undergo polygraph tests.
"All three have given their consent. They've absolutely no problem in undergoing the lie detector test. They don't have anything to hide. They have only requested that the guidelines of the Supreme Court should be followed when the test is conducted," Vikas Pahwa, a witnesses' lawyer told ANI.
A Special Investigation Team (SIT) of the Delhi Police earlier had said that Congress leader Shashi Tharoor's domestic help Narain Singh, driver Bajrangi and family friend Sanjay Dewan might be "hiding something" including "material facts" and asked a Delhi court for permission to subject them to a polygraph test.
Tharoor has been questioned thrice over the alleged murder of his wife, who was found dead in their hotel suite on January 17 last year, days after she publicly accused her husband of having an affair with Pakistani journalist, Mehr Tarar.
