New Delhi: The narco analysis test on Aftab Amin Poonawala, accused in Shraddha Walkar murder case in the national capital, will not be conducted on Monday (21 November), the Forensic Science Laboratory (FSL) said. The 28-year-old will have to undergo polygraph test before the narco test for which his consent is needed. “We are not conducting the narco test on Aftab today,” said FSL Assistant Director Sanjeev Gupta. Punit Puri, also an assistant director at the FSL, said: “Before narco test we need to conduct a polygraph test for which we need subject’s consent. Court has permitted narco test and for polygraph test we’re still awaiting permission. Once we receive permission, everything else will be done in 10 days.” “We have been directed by Delhi Police and our Director to process this case fast. We have been working on some parameters that are important before conducting the narco test,” Gupta said. Assistant Director Sanjeev Gupta further said they have received request for the narco test “and we have started our work as well. Our director Deepa Varma has instructed to take this case on priority.” “There was a meeting on Sunday between the FSL and the police team and everything has been decided but some parameters need to be completed before the narco test and they have been informed to the police. As soon they complete them we can do narco,” he said.

What is narco analysis test? Also known as truth serum, Narco analysis, involves intravenous administration of a drug (such as sodium pentothal, scopolamine and sodium amytal) that causes the person undergoing it to enter into various stages of anaesthesia. In the hypnotic stage, the person becomes less inhibited and is more likely to divulge information, which would usually not be revealed in the conscious state. Why is narco analysis test conducted? The narco analysis test is being conducted after other evidences do not provide a clear picture of the case to the investigating agencies. The Delhi Police had sought Aftab’s narco analysis test as his responses during interrogation were “deceptive” in nature. The Supreme Court has ruled that narco analysis, brain mapping and polygraph tests cannot be conducted on any person without his or her consent.

According to HowStuffWorks, in polygraph test four to six sensors are attached to a person who is taking the test. A polygraph is a machine that records multiple (“poly") signals from sensors on a single strip of moving paper (“graph"). The questioner asks three or four simple questions to establish the norms for the person’s signals when the polygraph test begins. The polygraph examiner then gradually puts forward the real questions and during this, all of the person’s signals are recorded on the moving paper throughout the interrogation.
