Anthony Joshua followed in the footsteps of some of the all-time great boxers as he beat Italy's Roberto Cammarelle to win Olympic gold in the super heavyweight division at the Excel Arena.
The Watford fighter went into the final round trailing by three points against the reigning Olympic champion, but he was able to turn the tables before eventually being awarded the contest on count back, with the scores level at 18-18.
Joshua emulated Audley Harrison, who won gold 12 years ago, while another former Olympic boxing champion, Lennox Lewis, watched on.
The 22-year-old, who only took up the sport four years ago, capped a fantastic Olympics for GB's boxing team, who won five medals in total, including three golds.
"Once again, there are no easy fights in these Olympics. I have pulled it out of the bag and my heart is pumping with adrenaline. The third round is always a good round for me. Again and again, the crowd have come out," said Joshua.
"Sunday is a holy day and I have been blessed. I want to gain more experience and keep on pushing. I am still an amateur. That medal represents my journey and the support from my team. It is much more than a gold medal, it is a life experience. It is not just me, it is my fallen soldiers and the ones who have made it."
Earlier in the day, welterweight Freddie Evans was unable to claim gold as Serik Sapiyev of Kazakhstan outboxed the Welshman throughout to emerge the clear victor.
Sapiyev came out on top 17-9 but there was plenty to celebrate for Evans who claimed silver and became the first man from Wales to win a boxing medal since 1972.
"I have had four hard fights and that was the fifth. No excuses, he was sharper and I did not stick to my plan correctly. He was sharper today and he came out on top. I am still young at 21, so I have done well and I am over the moon," said Evans.
