New Delhi, Dec 9 : The Saket Court on Friday extended Aaftab Amin Poonawalla's judicial custody for 14 days after the Delhi Police submitted that the investigation into the Shraddha Walkar murder case is in progress and requested for extension. Poonawalla, who killed his live-in partner Shraddha on May 18 and then chopped her body into 35 pieces, is currently lodged in Tihar Jail. On November 26, he was sent to a 13-day judicial custody by the court. On December 2, Poonawalla's narco test got over. It was conducted by Forensic Science Laboratory officials inside the prison. Though his confessions in the narco test cannot be used in court, it proved that the investigators were proceeding in the right direction. Findings of both polygraph and narco test are not admissible in the court. These tests will only help the Delhi Police gather evidence, and thereby increase the possibility of prosecution of the guilty. /IANS
