On November 15, the woman approached KN Katju police station in Delhi's Rohini area with a complaint alleging that she had been raped the night before.
She told the police that around midnight, she took a taxi from near Ansal Plaza, a prominent landmark in south Delhi, to go to her home in Rohini, in north-west Delhi. The taxi driver, she alleged, allowed another person to board the taxi and soon, they started misbehaving with her, the police said.
The two men threatened her and took her to Greater Noida where they raped her. They also took away her gold ornaments, mobile phone and Rs 12,000 in cash, the police said.
She managed to reach home and informed her family and subsequently a complaint was lodged with the police.
Since the woman boarded the taxi from Ansal Plaza, which falls under the jurisdiction of Hauz Khas police station in Delhi, a case was registered there.
An investigation is currently under way, an officer said.
More details are awaited.
