The ruling Communist Party's anti-graft body says on its website that Huang Yurong had turned herself in on Saturday at Beijing's Capital Airport. Photos on the website show Huang flanked by police in civilian clothes standing before an official and signing a document.
Huang is accused of abusing her position as head of the highway administration in the central province of Henan to embezzle funds and take bribes. She fled abroad in August 2002.
