Indian boxing legend M.C. Mary Kom scripted history by clinching a record sixth World Championship Gold medal in the light flyweight 48 kilogram category after outclassing Ukraine's Hanna Okhota 5:0 at the K.D. Jadhav Indoor Stadium here on Saturday. The 35-year-old Mary, a mother of three and a pre-tournament favourite for the gold, rewrote the record books when she eclipsed her joint haul of five golds with Katie Taylor of Ireland. The Manipuri pugilist, who went over her weight category to clinch a 51kg bronze at the London Olympics, previously clinched the World Championship gold on five occasions -- 2002, 2005, 2006, 2008, 2010 -- besides bagging a silver on her debut in 2001.
