It was a September day in 2012 when Manti Te’o was told his beloved grandmother had passed away.
Just hours later, the American college football player was hit with more tragic news.
His girlfriend, Lennay Kekua, had died from leukemia, after surviving a near-fatal car accident months earlier.
A rising Notre Dame football star, Te’o's devastating loss quickly made headlines around the country.
Three days later, the athlete was hailed a hero when he bravely took to the field and led his football team, the Fighting Irish, to an incredible victory.
At the time, Te’o was simply fulfilling a promise he had made earlier to Kekua, who he had been dating online for around a year.
"Promise that you'll stay there and you'll play and you'll honour me through the way you play," the 22-year-old Stanford university student told him before she passed.
But months later, it would be revealed that Kekua didn't die that September day. In fact, she never existed.
10 years on, the true story behind the scandal which rocked America's sporting world is being told in Netflix's new documentary, Untold: The Girlfriend Who Didn't Exist.
The two-part documentary, which features interviews with both Te’o and the person behind the hoax, tells the infamous catfishing tale that sent the football player's "life and career spiraling".
