HONG KONG - A RELATIVE of Macau chief executive Edmund Ho is wanted by Interpol in the latest twist in the city's biggest graft scandal.

The international police organisation has issued a 'red notice' for Chan Lin Ian, brother-in-law of Mr Ho's brother, and his wife Lam Man I over suspected money laundering.

Arrest warrants for the pair have also been issued by the Macau authorities, according to the Interpol website.

A red notice means that the people concerned are wanted by national jurisdictions, and that Interpol will assist the national police forces in identifying or locating them.

Chan, 53, has been implicated in the corruption case of Macau's former public works minister Ao Man Long, who was jailed last year for 27 years on 57 counts of bribe-taking, money laundering, abuse of power and other charges, Hong Kong's Sunday Morning Post said.

Chan's company, Shun Heng Construction, came under investigation last year after it allegedly provided kickbacks to Ao over three public works projects it undertook between 2003 and 2006.

Chan was among 13 suspects whose cases were sent to the Public Prosecutions Office last April in relation to the Ao scandal.

Macau residents have been calling on the commission to investigate further.

Interpol has so far issued a total of six red notices for people allegedly involved with Ao's case, including his wife, Chan Meng Ieng, the report said.

Ao, who was arrested in December 2006 by the Macau Commission Against Corruption, amassed a personal fortune of more than US$100million (S$149million) during his seven years in office - 57 times his family's income during that time. -- AFP
