Buying meals is how we show respect, says Heung Yee Kuk chief Anti-graft officers yesterday arrested another 10 men over vote-rigging allegations on the third day of a crackdown that has forced the postponement of elections to a Yuen Long rural committee. The ICAC said its inquiry concerned allegations electors were bribed, refreshments and entertainment provided at elections, force or duress was used against electors and election expenses were put to illegal use. The chairman of rural affairs body the Heung Yee Kuk, Lau Wong-fat, would not comment on the arrests, but said there was a tradition of hospitality among villagers, who treated each other to drinks and meals and to show respect to their elders. The arrest yesterday of nine village heads and a businessman took to 50 the number of village heads held. An Independent Commission Against Corruption spokeswoman said the operation, one of the city's biggest against election-related corruption, was continuing. She said the village representatives arrested under the Elections (Corruption and Illegal Conduct) Ordinance were among 71 eligible to vote in the rural committee election for Shap Pat Heung, in which village heads choose representatives to manage rural affairs. Two of the village heads detained - Leung Fuk-yuen and Tsang Ma-ming - were contesting the chairmanship of the committee, a source said. It is understood Leung and some of the village heads were arrested at a hotel on Sunday night. The kuk's Mr Lau said: 'There are treats of meals and these are the traditions of showing respect to the older generation. I know this could be problematic,' he said. 'We have learned our lesson after this incident.' The rural leader, who is also a legislator, urged the government to do more to educate villagers about corruption. Patrick Ho Chi-ping, the secretary for home affairs, said the government would study whether to bring rural committee elections under a statutory framework. Last night, more than 30 suspects, including Mr Leung and Mr Tsang, were still being held for questioning at ICAC headquarters in Central. The others have been released on bail pending further investigation. The ICAC raids came after Mr Leung lodged a complaint to police last week saying he and his supporters had been harassed.
