Delhi Police has seized five knives from the flat of Mehrauli murder accused Aaftab Amin Poonawala, who underwent a marathon polygraph test of nearly eight hours on Thursday.
However, police said the saw allegedly used by Poonawala to cut his live-in partner Shraddha Walkar's body is yet to be recovered.
The incident also took a political turn with Union Home Minister Amit Shah assuring "strict punishment" to the accused in minimal possible time while the CPI-M alleged that the murder and dismemberment of Walker by her Muslim boyfriend was being used for "communal propaganda".
According to the sources in the police department, the recovered knives were sent to FSL for examination to ascertain if these were used in commission of the crime.
"If these knives were used during commission of the crime, will be ascertained only after forensic examination which takes time," said a source.
The second session of the polygraph test of Poonawala which started around 12 pm at the FSL Rohini went on for nearly eight hours.
"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. He was also asked about 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," an FSL source said.
