Hungary's Katinka Hosszu has extended her lead in the FINA World Cup by grabbing eight medals in the Hong Kong leg of the series.

On the opening day of the event, the 26-year-old won five titles, and added to her success on the final day by taking gold in the women's 200m butterfly final.

Victories in the 400m freestyle and 400m individual medley rounded off Hosszu's successful campaign in China.
