Joel Gonzalez delivered a masterful performance to earn Spain's first-ever Olympic gold medal in taekwondo, while compatriot Brigitte Yagüe garnered the silver in her category at the 2012 London Games.
Gonzalez defeated South Korea's Lee Dae-hoon, the 2011 world champion in bantamweight, in Wednesday's final of the men's flyweight (58kg).
The 22-year-old Spaniard, already a two-time world-champion in flyweight, took a 1-0 lead at the start of the first round and a kick to his opponent's head gave him another three points, which were awarded after Gonzalez's coach alerted the referees.
The instant replay showed the coach to be correct, although the decision was greeted by boos from one section of the crowd at London's ExCeL Arena.
Down on the scoreboard, Lee was forced to attack and managed to outpoint the Spaniard during the remainder of the first round, which ended with Gonzalez on top 5-2.
Lee was repeatedly punished for his attacks in the second and third rounds, on one occasion being sent to the canvas and having to receive medical assistance, as Gonzalez stretched his lead to 8-4.
In the final seconds, the Spaniard was able to avoid bout-altering kicks to the face - worth as much as four points - while continuing to score on the counter-attack to win 17-8.
Yagüe, meanwhile, lost to China's Wu Jingyu on Wednesday and wound up with the silver in the women's flyweight (49kg) category.
The 31-year-old Spanish athlete, a three-time world champion, finally got her long-awaited Olympic medal after bad luck had cost her in the past. She lost her first bout of the Athens Games in 2004 when there was still no seeding and then was unable to participate in Beijing due to a broken hand.
Wu, who also won gold in Beijing, used her speed and technical skill to score an 8-1 victory in the final.
Spanish Prime Minister Mariano Rajoy on Thursday sent congratulatory messages to both Gonzalez and Yagüe.
He praised both athletes for the "talent, work and effort" that have given them a "prominent place" in the history of Spanish sport and raised Spain's global stature. EFE
