Britain's Libby Clegg clinched her second gold medal at Rio 2016 by adding the women's 200m T11 crown to her 100m title as Brazilian Paralympic icon Terezinha Guilhermina was again disqualified on a dramatic day of athletics action at the Olympic Stadium.

Clegg, along with guide Chris Clarke, broke clear after the bend on her way to crossing the line in a Paralympic record time of 24.51sec ahead of Chinese duo Liu Cuiqing and Guohua Zhou.

The triumph for the 26-year-old, who has lit up the athletics events at the Games with her fearless displays, saw her dethrone three-time Paralympic gold medallist Guilhermina, whose disappointing Rio 2016 campaign continued.

Guilhermina, who was bidding for a third consecutive gold in the 200m competition having won the race at Beijing 2008 and London 2012, perhaps succumbed to the weight of expectation on her shoulders as she went off a fraction too early and was given a false start.

"I had never had a false start in 16 years of career and fate decided that I was going to do it today in a Paralympic final at home," the Brazilian said.

"I forgive myself because I'm human. 

"It was an accident. 

"I did not go out from home thinking that I am going to crash my car, but it happens."

While Guilhermina struggled, another high-profile Paralympic athlete continued to thrive as Tatyana McFadden matched the achievement of Clegg by claiming a second gold medal of the Games.

The formidable American powered to her fifth Paralympic title, racing home in a Paralympic record of 3min 22.50 in the women's 1,500m T54.

The 27-year-old Russian born athlete spearheaded an American clean sweep as Amanda McGrory was second, with Chelsea McClammer rounding off the podium.

It proved to be yet another record breaking day at the Olympic Stadium as Davendra regained the men's javelin F46 title 12 years after winning gold at Athens 2004 in style.

The Indian athlete, who lost his left hand after touching an electric wire while climbing a tree at the age of eight, broke his own world record on his third attempt, launching the spear a colossal 63.97 metres to earn what was only his country's fourth Paralympic gold medal in history.

Guo Chunliang added to the Chinese haul with silver, while D.P Herath Mudiyanselage of Sri Lanka took home the bronze.

Oksana Zubkovska then cemented her status as the undisputed queen of the women's long jump T12 event as the Ukrainian successfully defended a title she has held since Beijing 2008.

Zubkovska saved the best until last, producing her furthest effort of 6.11m on her sixth and final attempt when victory was already assured.

Elena Chebanu also recorded her best jump in the sixth round as she leapt into silver medal position with 5.56m, narrowly in front of bronze medallist Lynda Hamri of Algeria, who was three centimetres short in third place.
