Nine postal workers have been arrested over an alleged $1 million scam to arrange bogus business transactions for Speedpost services. A superintendent, a senior officer, five postal officers and two postmen were arrested by the Independent Commission Against Corruption. Five others - the wife of one of the postal officers, a former postal officer, a clerk and two drivers - were also arrested. The ICAC said Hong Kong Post alleged some postal staff might have accepted advantages to connive in a scam to obtain cash through bogus credit card transactions. Between January last year and March this year the arrested postal staff allegedly obtained $1 million cash proceeds paid by customers using Speedpost service. In order to balance the books, the postal staff were alleged to have used 38 credit cards, belonging to themselves, their spouses or other persons, to create 470 bogus business transactions worth the same amount. The suspects allegedly gained from the scam by obtaining reward points to redeem gifts from credit card companies through these bogus transactions.
