Battling boxer Luke Campbell earned Team GB another gold after a noisy Anglo-Irish tear-up at London 2012.
Campbell, 24, from Hull, overcame Ireland's John Joe Nevin who had to settle for silver in the 56kg bantamweight competition.
Home favourite Campbell was cheered on by a passionate local support - equally matched by followers of Irish traveller Nevin.
He told the BBC: "It was just about outwitting each other tonight. He (Nevin) is a very strong fighter, so I had to be aware.
"I had to be on my game to win and I was on my game tonight. I can’t believe it, I really can't. I’m very proud to be from Hull."

But it was the Union flags held highest after judges gave the decision 14-11 to Campbell to the delight of the majority of the 10,000 sell-out crowd at the ExCel arena.
Campbell raised his hands in triumph - then burst into tears as the crowd chanted "Campbell! Campbell!"
