Ireland's Kellie Harrington has won a gold medal in the lightweight division at the AIBA Women's World Boxing Championships following victory over Thailand's Sudaporn Seesondee.

The Dubliner got the nod on a split decision in New Delhi to become the third Irish boxer after Michael Conlan and Katie Taylor to win gold at world level. 

Two years ago, Harrington took home silver at the Worlds in the light welterweight division.

She won on a 3-2 decision to go one better this time, collapsing into her corner in delight and saluting the Irish support.

"I'm still kind of numb right now to be honest," she said afterwards.

"It won't really hit home until I get home. It's been a long process since 2016. I wanted to come back and get a gold. I said I'd come back and get it.

"Sometimes when people say they don't believe it. I said it and I believed it. I worked in silence, came back and did the job."

In a cagey opening round, Seesondee prodded early but neither fighter landed anything major. Harrington landed some decent combinations late on in a decent finish to a tight round form the Dubliner.

Harrington moved smoothly in the second, landing a great right after a slick combination but her Thai opponent also landed some decent shots in another close round.

Seesondee was more aggressive in the final round. Good head movement from Harrington saw her evade the biggest punches mid-round and the Irishwoman finished strongly with a nice connect before the bell.
