Gallant rescue efforts were wasted on at least one village. Responding to a distress call, four uniformed constables went to Siu Hang Tsuen and found bridges as high as two metres submerged. With most of the 20 or so families trapped in their homes, they stripped down to their green trousers and were about to dive in when a team of the elite Special Duties Unit divers arrived in a speedboat. The commandos took over and pulled several people out, only for one man to tell them their help was not needed. One of the men said most families were used to flooding and were waiting for the water to subside. He told police he was going to the grocery store. 'Most families are not exactly trapped. We're used to seasonal floods,' he said. 'We're waiting inside our houses. The water should subside before the evening.' But a villager, surnamed Wong, from Ho Sheung Heung in Sheung Shui, told a radio interviewer he called police because he feared for his safety. 'The flooding is unusually severe,' he said. 'Water in my house was up to my waist.'
