This sounds like something out of a very bad movie indeed. Valiant prisoner competes in a sport and by winning also wins their freedom. In fact, haven't there been many movies with that plot line?
Thai inmate Samson Sor Siriporn boosted her chances of freedom by beating Japan's Ayaka Miyano to win the vacant women's WBC light-flyweight title at the notorious "Bangkok Hilton" prison Tuesday.
Under the gaze of dozens of prison guards, Siriporn, a convicted drugs dealer, battled through the unforgiving Thai heat to score a unanimous points victory and kick-start parole proceedings for her early release.
"I've been in jail for a long time now, I hope this will see me released early," said Siriporn, flanked by mean-looking guards and surrounded by photographers.
"When I'm free I'll carry on fighting. I want to fight all over the world."
Fighting in a makeshift ring in the grounds of the infamous Klong Prem prison with the Thai crowd chanting "fight, fight," Siriporn was on the attack from the start and repeatedly forced Miyano on to the ropes with a barrage of punches.
The intense afternoon heat took its toll on Miyano, who twice fell to the canvas as a result of Siriporn's relentless attacks, which drew rapturous applause from the few thousand prison staff, factory workers and taxi drivers who flocked to see her fight for freedom.
Despite the fact that the movie has already been made I'd bet more than a few dollars that there's some studio exec half-way over the Pacific right now with a contract for the movie rights to the story clutched in his sweaty little paws.
