The victim, 17 then, had gone with her boyfriend Ashish to the Buddha Jayanti Park near Rashtrapati Bhavan Oct 6, 2003. She was raped by Harpreet and Satender while the other two - Kuldeep and Manish - kept a watch.
The four first roughed up Ashish and then took the girl to a secluded place inside the park where they raped her, the prosecution said.
