Eighteen men and nine women were detained during a raid on the offices of Million Profit (Far East) in Jaffe Road, Wan Chai, after investigations into an alleged London silver trading scam involving $5 million. The raid was mounted after police received 15 complaints from people allegedly lured into investing into trading after they were employed as clerks and cleaning workers who had invested sums between $40,000 to $500,000, police said.
