A female Thai prisoner has boosted her chances of freedom by winning the world light flyweight boxing title.
Samson Sor Siriporn, a convicted drug dealer, beat Japan's Ayaka Miyano in a bout staged at the mixed Klong Prem jail, known as the "Bangkok Hilton".
Watched by dozens of prison staff, Siriporn won on points after 10 rounds in the ring, kick-starting parole proceedings for her early release.
The 24-year-old took up boxing to protect herself from violent inmates.
Siriporn, serving a 10-year sentence for selling small amounts of drugs, dominated the fight.
