A man who claimed his wife had been duped into buying hundreds of thousands of dollars worth of fragrance products was arrested by police yesterday after he stormed into a Causeway Bay office brandishing a knife and holding flammable liquid. Police said the 32-year-old charged into the Hennessy Road office of Digital Crown Holdings, in East Point Centre, just before 3pm carrying a 40cm knife and a can of flammable liquid. The man, surnamed Cheung, said his wife had enrolled in the company's sales training scheme and bought HK$200,000 worth of products from the company, which is the local distributor of the century-old French oil-burner fragrance Lampe Berger. He claimed his wife had been duped into buying the company's products and demanded the staff give them a refund. When his request was rejected, the man became emotional and staff members called police. When police arrived at the office with fire service officers, they found the man sitting on a chair in the reception area. He was holding the knife in his hand, with the can of flammable liquid lying beside him, they said. Police arrested the suspect for possessing offensive weapons and took him to Wan Chai police station for questioning. No one was hurt during the incident. A police spokesman said the man would be held overnight. Police gave no further details about the standoff before they arrived at the office and they would not confirm reports that two company workers were helping with their inquiries. A Digital Crown Holdings staff member last night said the company would not issue a formal comment on the incident. In 2001, the company sued Express Weekly magazine for unspecified damages over reports concerning allegations that it was engaged in pyramid selling tactics.
