It emerged after he was appointed to the board investigation that Dinh is godfather to one of Lachlan Murdoch's children and friend of Lachlan since 2003. Further, in 1992, a decade before he met Lachlan, Dinh wrote of his sister, held in a Hong Kong refugee camp, in the "New York Times", which led to NBC TV coverage and then to a series of articles in the "South China Morning Post". The "Post" was owned by Rupert Murdoch, and Dinh's articles there were credited with helping free his sister. The personal ties to Murdoch interests and family were debated as Dinh took the role in the phone-hacking investigation.
