Two forensic experts, who had provided scientific support and services in the probe into the December 16 gang rape case, were cross-examined by the defence counsel in a Delhi court.
BK Mohapatra, senior scientific officer, and Rajender Singh, a principal scientific officer who is also an assistant chemical examiner, were cross-examined. Both work at the Central Forensic Science Laboratory.
The statement of both the experts were recorded by Additional Sessions Judge (Fast Track Court) Yogesh Khanna during in-camera proceedings.
Two other witnesses - Rashmi Ahuja from Safdarjung Hospital and Delhi Police head constable Giri Raj who took accused Pawan Gupta for medical examination - also testified as prosecution witnesses.
Ahuja had initially prepared Medico Legal Case (MLC) of the victim, describing her wounds and injuries caused during the commission of the crime.
