The male friend and the sole eyewitness to the December 16 brutal assault and gangrape of the victim in a moving bus was on Monday cross-examined by the defence in the fast-track court trying the case in New Delhi.
The youth, a software engineer, who had testified as a witness for the prosecution during in-camera proceedings against the five accused who have pleaded not guilty to the charges of rape and murder framed against them, was cross-examined by the counsel for accused Pawan Gupta.
His cross-examination will continue on Tuesday.
The victim's friend arrived before Additional Sessions Judge Yogesh Khanna in a wheelchair because of the injuries inflicted on him in the heinous attack of December 16, 2012.
Apart from the victim's friend, three others -- including a person who had seen the accused destroying the evidence after commission of the crime -- have already deposed in the court.
Meanwhile, the court will record the evidence of the youth and four others including the magistrate, who was part of the judicial proceedings relating to the test identification parade of the accused.
The 23-year-old girl had died on December 29, 2012, in a Singapore hospital as a result of the grievous injuries she had suffered when she was sexually assaulted by six people, one of whom has been declared as a juvenile.
