Five knives used by Aaftab Poonawala to dismember Shraddha Walkar's body after killing her have been found, and a saw is still missing, the Delhi Police claimed, in the latest revelations into the gruesome killing that has stunned the country.
The police said they have recovered five knives, each between 5-6 inches long, and they have been sent for forensic examination.
Aaftab Poonawala is accused of strangling his girlfriend Shraddha Walkar earlier this year and chopping up her body into 35 pieces, which he kept in a 300-litre fridge for almost three weeks at his residence in South Delhi's Mehrauli before dumping them across the city over several days.
Commenting on the crime for the first time, Union Home Minister Amit Shah on Thursday assured "strict punishment" to the guilty in the fastest possible time, while the CPI-M alleged that the incident was being used for "communal propaganda".
Poonawala, meanwhile, appeared for a second session of a polygraph test which started around 12 pm at a forensic lab in Delhi and went on for nearly eight hours, news agency PTI reported.
"During the session, Poonawala was asked details about the case, what triggered him to kill Walker, if it was a planned event, or he did it in a fit of rage like he claimed in the court. All the sequence of event that transpired ever since they started dating and how he decided to dispose of the body in such a gruesome manner," PTI quoted a source as saying.
"He was also asked about the kind of weapon he used to chop her body into multiple parts, along with various other questions related to the case that could give lead to further investigation in the case," the source said.
The test could not be conducted on Wednesday as Poonawala was had fever and cold.
The accused had undergone the first session of the polygraph test, also known as the lie detector test, on Tuesday.
