In October 2016, Zulfiya CHINSHANLO of Kazakhstan, competing in the Women's 53kg Weightlifting event, in which she ranked first and for which she was awarded the gold medal, has been disqualified from the Games of the XXX Olympiad.
Camille Muffat clinched the women's 400m Freestyle title with a wonderfully aggressive swim - as Great Britain's Rebecca Adlington took bronze - before, in the final race of the night, Yannick Agnel powered past USA's Ryan Lochte in the final 10m to hand them gold in the 4 x 100m Freestyle Relay.
The evening's action started with an equally-stunning display from USA's Dana Vollmer, who smashed the world record - she swam 55.98 - to claim gold in the 100m Butterfly.
Another world record went in the men's 100m Breaststroke as South African Cameron van der Burgh obliterated the opposition to win in 58.46.
The United States' men's Basketball team lived up to their dominant reputation with a 98-71 rout of France in their opening game.
Although the French, who have plenty of NBA-calibre talent in their squad, were able to match them for the first quarter, the defending champions quickly began to wear them down thereafter.
Kevin Durant led the Americans with 22 points while Kevin Love had 14 and Kobe Bryant 10. Durant added nine rebounds.
Brazil beat Australia 75-71, Nigeria held on to see off Tunisia 60-56, Spain eased past China 97-81 and Russia overcame hosts Great Britain 95-75.
Marianne Vos edged out Lizzie Armitstead in a thrilling sprint finish to win the women's Road Race.
Vos, 25, needed all of her power to deny Great Britain star Armitstead a home victory at London 2012 after they and Russian Olga Zabelinskaya were left after a four-strong breakaway, guaranteeing themselves at least a medal after a wet 140km ride.
And it was Dutchwoman Vos who ended her six-year wait to add to her 2006 world title after five World Championship silvers with a time of 3:35.29.
In the Hockey, Olympic women's champions Holland beat Belgium 3-0, New Zealand edged out Antipodean neighbours Australia 1-0 and world champions Argentina thrashed South Africa 7-1.

It means Rhode is the first American to win an individual sport medal at five consecutive Olympic Games.
North Korea's An Kum Ae won Judo gold with a sudden-death victory over Cuban Yanet Bermoy Acosta in the women's -52kg final at ExCeL.

China's Wu Minxia hailed a 'marvellous miracle' after she secured her place in Olympic Games history with a hat-trick of springboard synchro titles alongside He Zi at the Aquatics Centre.
Wu cemented her place as one of the greatest female divers of all time as she also drew level with former synchro partner Guo Jingjing, who she teamed up with to win the past two Olympic crowns, with a record six medals at the Games.
The 26-year-old, whose early career was blighted by injury, could even surpass that mark next week when she and He go head-to-head in the individual springboard.
