Spain's World Championships silver medallist Javier Pérez Polo achieved gold in the men's under-68kg, while Italy's Simone Alessio claimed the men's under-80kg title.

Gbagbi of Ivory Coast won the final bout 2-0 after a spinning kick landed on the South Korean in the final seconds of the first round to take the advantage before comfortably winning in the second.

This was Nam's first Grand Prix final following her debut semi-final clash versus Mexico's Leslie Soltero, where she sealed a 2-0 victory.

Belgium's world junior champion Sarah Chaari joined Soltero in securing bronze, having lost 2-1 to Gbagbi.

Plenty of key names fell to early defeats in the women's under-67kg competition, including Spain's European champion Cecilia Castro Burgos, who exited in the first round.

Croatia's Nika Klepac, who entered as the 25th seed, overcame the eighth seed in a 2-0 win, while Pan American Championships gold medallist Milena Titoneli of Brazil lost to the same result versus Nam as her opponent began her surge to the final.

Tokyo 2020 Olympic champion and top seed Matea Jelić, also representing Croatia, was unable to progress past the round of 16 due to a 2-1 defeat to Soltero.

Britain's Olympic silver medallist Lauren Williams entered the competition as the third seed but also could not progress to the quarter-finals having lost 2-0 to South Korea's Kim Jan-di.

There was also disappointment for the home nation as second seed Magda Weit-Hénin could not follow up her heroics that saw her win silver at the European Championships in Manchester in May.

Her quarter-final bout versus Chaari ended 2-1 to the Belgian.

In the men's under-68kg category, Pérez Polo stood top of the podium following his 2-0 triumph versus Jordan's Zaid Kareem.

Experience paid dividend to the victorious Spaniard as he sealed a 7-0 first round win before taking the second 9-4.

Britain's top seed Bradly Sinden, a silver medallist at Tokyo 2020, and France's Théo Lucien settled for bronze medals after they both registered 2-0 defeats to Kareem and Pérez Polo.

Big names were toppled earlier in the under-68kg weight category, with second seed Hakan Reçber of Turkey, fourth seed Edival Pontes of Brazil and fifth seed Bernardo Pié of Dominican Republic all losing in the round of 16.

Reçber, an Olympic silver medallist and a winner at the Rome Grand Prix, was swept aside 2-0 by Hungary's Levente Jozsa as Pontes lost to the same result against Kareem.

Meanwhile, Pan American champion Pié was beaten 2-1 against the hosts' Dylan Chellamootoo.

In the men's under-80kg class, second seed Alessio was taken the distance by Norway's eighth seed Richard André Ordemann but ultimately came out triumphant.

Tunisia's Firas Katousi finished with a bronze after falling to a 2-1 defeat to Ordemann while the United States' Carl Nickolas lost 2-0 to Alessio to secure the other bronze, which was the first of his Grand Prix career.

Nickolas' and Alessio's bout had a hint of controversy as the Italian had three points judged invalid because it was ruled he used his hands illegally during a combination of moves between the two fighters.

Nickolas was awarded a penalty so instead of going 3-1 up, Alessio was 2-0 down.

The incident left the American with a blooded noise, which he received treatment for.

Despite the setback, Alessio ended up winning both rounds to cruise into the final.

During the earlier rounds of the weight division, Olympic medallists were forced to take earlier showers than they would have liked.

Katousi overwhelmed Croatia's Toni Kanaet 2-1 in the round of 16 while Jordan’s Saleh El-Sharabaty and Egypt’s Seif Eissa were beaten 2-1 and 2-0 by Ordemann and Nickolas.

The Paris World Taekwondo Grand Prix is due to continue with the men's over-80kg and women's over-67kg classes.
