Mary Kom, however, had to settle for the bronze as she went down fighting in her 51kg semi-final bout against local favourite Nicola Adams.
The 29-year-old Manipuri also became the second Indian boxer after Vijender Singh to win an Olympic medal. Vijender got a bronze in Beijing fours years ago.
Buoyed by the presence of British Prime Minister David Cameron and star professional boxer Amir Khan, second-seed Nicola put on a flawless performance while beating the Indian 11-6 at the packed ExCel Arena.
