A special court in Ghaziabad granted permission to CBI to conduct narco analysis test on Rajesh and Nupur Talwar -- parents of 14-year-old Aarushi who was found dead under mysterious circumstances at her Noida residence less than two years ago.
Special Judicial Magistrate Preeti Singh granted the permission on an application filed by CBI about two weeks back.
Aarushi and domestic help Hemraj were found murdered in her Noida house on May 16, 2008.
The CBI, which has re-constituted its entire investigating team to probe the case, had earlier taken a written permission from the Talwars for conducting the tests on them.
Narco analysis involves psychotherapy which is conducted while the patient is deeply sedated with medication so that inhibitions are reduced and responses more truthful.
Incidentally, Rajesh, who was arrested by the Noida police, was let off after the CBI gave him a clean chit.
