Jarno has been raising funds since April to help those affected by the earthquake in his home region of Abruzzo, collecting donations via www.abruzzonelcuore.net, organising a charity football match and hosting auctions of memorabilia, the latest of which occurred on Wednesday night.
Among the lots on offer at the exclusive VIP event in Singapore was a Jarno helmet as well as racing helmets from Mark Webber and David Coulthard while Audemars Piguet donated a unique watch which raised Euro150,000 alone.
Jarno said: "It was another great event and I would like to thank everyone who took part, especially Audemars Piguet. This money is really important for the people of Abruzzo and it will help to rebuild the community, which suffered so much damage in the earthquake. I have put a lot of energy into this charity project and I will personally make sure the money is well spent to make the people's lives better."
