TWO French Chinese tourists have been robbed of cash and valuables worth $476,000 inside their Grand Hyatt hotel suite in Wan Chai. Police said a man delivering a bouquet of flowers knocked on the door of the women's room at about 10 am yesterday. When one of the victims opened the door three other men suddenly pushed her inside, where she and her companion had their hands tied with metal wires. The victims, aged 38 and 40, had their heads covered with a quilt. The gang, one of whom had a knife, then ransacked their room. The women later told police that three diamond rings worth US$58,000 (about HK$449,700) were snatched. Also lost were HK$4,000 and US$3,000. The tourists arrived last Saturday and were due to leave next Monday. Police are hunting the four aged between 30 and 40, of dark complexion and believed to be Asians. Grand Hyatt's general manager, Peter Jentes, said they would launch an internal investigation as to why an outsider managed to deliver flowers to a guest. He said normally all outside deliveries must go through the concierge. ''Details such as to whom the package or flowers are for, who it is from, contact phone number and/or business card of sender, and contents of the package are all taken down by our concierge staff. ''Once the above has been fulfilled, then the package/flowers is delivered, by one of our staff, to the guest room,'' he said. It was the first robbery in the hotel since its opening four years ago. Mr Jentes said whether security would be stepped up in future would depend on the findings of their review and police investigations.
