A court in Delhi on Tuesday gave Delhi Police permission to conduct a polygraph test on Aftab Poonawala, who allegedly killed and dismembered the body of his live-in partner Shraddha Walkar, reported news agency PTI.

Delhi Police had moved its application in court on Monday.

"Yes. We have received permission from the Delhi Court to conduct a polygraph test on Poonawala," a police official told PTI.

A polygraph test is a non-invasive technique in which no medicine is used. The subject is attached to a machine and questions are asked to him/her about the matter related to any case or incident. The variation in the graph when the subject answers the questions are mapped to draw a conclusion.

According to the American Psychological Association (APA), polygraph tests measure a person's "heart rate/blood pressure, respiration, and skin conductivity". The purpose of the test is usually to prove whether or not a person committed a crime, reported PTI.

Poonawala, 28, allegedly strangled his live-in partner Shradha Walkar and sawed her body into 35 pieces which he kept in a fridge for almost three weeks at his residence in South Delhi's Mehrauli locality. He later disposed of the body parts across the city over several days.
