<p>The harrowing Delhi murder case of Shradha Walkar continues to unravel with shocking details, as part of which the police have now sought a narco test of the accused Aaftab Amin Poonawala.</p>.<p>Investigators claim that a narco test is necessary as Poonawala is changing his statements and not cooperating with the probe. But first, let us understand what is a narco test.</p>.<p><strong>What is a narco test?</strong></p>.<p>As part of a narco test, sodium pentothal, also called ‘truth serum’, is injected into a person. Doing this lowers a person’s self-consciousness, thereby allowing them to speak without inhibition. The person is said to be in a hypnotic state after this drug administration.
