Exclusive | Exclusive: Net closes on Ling Jihua, one-time top aide to ex-president Hu Jintao
Graft-busters on the mainland investigate a second sibling of Ling Jihua in sign that he will become the next target of Xi Jinping's campaign
Graft-busters on the mainland are closing the net around a powerful family headed by Ling Jihua, for long the right-hand man of former president Hu Jintao.
Ling Wancheng , the youngest of the five Ling siblings, recently left China for the United States via Hong Kong and Singapore but has since returned to the mainland, where he is under investigation, sources say.
It is not clear if the businessman, better known as Wang Cheng, returned of his own volition or as a result of cooperation between China and the US.
Hu has been conspicuously silent over the investigation.
The detention of Ling Wancheng will help authorities prepare a move against Ling Jihua, the second-youngest and most powerful of the five siblings. Sources said the investigation against Ling Jihua could start soon after the Communist Party leadership wraps up its agenda-setting meeting today.
