Roscommon's Lisa O'Rourke wins gold at world boxing championships

Roscommon has a champion of the world, after Lisa O'Rourke earned gold at the IBA Women's World Boxing Championships in Istanbul today.

It's a sensational achievement for the 20-year-old from Castlerea, who defeated Mozambique's Helena Alcinda Panguane on a 4-1 majority decision in today's final.

It was one of two Irish gold medals on a memorable day for the sport in this country, with Amy Broadhurst winning her 60-63kg final shortly before O'Rourke climbed through the ropes for the 66-70kg decider.

Prior to today, Katie Taylor and Kellie Harrington were the only Irish female boxers to have taken home gold medals from the world championships.

On social media, messages congratulating Lisa O'Rourke on her victory have been pouring in:
