A police inspector was driven to commit immigration offences because he needed money to fund his luxury lifestyle, a court heard yesterday. Deputy Judge Gary Tallentire jailed Petrus Yau for 42 months for submitting false documents to the Immigration Department to help two maids stay in the territory. He told Yau his crime was serious and was committed for monetary gain. The judge said the defendant, who earned more than $50,000 a month as a senior inspector, had lived beyond his means. Yau had a three-storey house in Yuen Long with a swimming pool, garden and two cars. He had three domestic helpers and kept three large dogs. He had to pay $20,000 a month to his divorced wife and a son who emigrated to England. Yau, 41, owner of the Jade Services employment agency in Yuen Long, forged domestic employment contracts and made false statements to the Immigration Department. Yau arranged for two Filipinos to come as domestic helpers for bogus employers. He was found guilty in the District Court of two charges of forgery, four of aiding and abetting a breach of condition of stay, and four of aiding and abetting the making of a false statement. Yau, who has been suspended from the force, maintained his innocence and vowed to appeal. He received a suspended 18-month sentence for theft in June and was fined for $8,000 for possessing ammunition without a licence.
