TAXI drivers called yesterday for more police roadblocks at night after an increasing number of attacks by passengers. Last year saw 213 drivers robbed by passengers. So far this year, 207 robberies have been reported. Drivers in rural areas said they were most vulnerable. The New Territories South reported 67 robberies in the first nine months of this year compared to 35 for the whole of 1994. A driver was stabbed to death in a remote area of Yuen Long last Friday. The taxi drivers' branch of the Motor Transport Workers' General Union lobbied the Crime Prevention Bureau at Police Headquarters yesterday calling for tougher measures to ensure their safety. 'Police promised to strengthen patrols at the crime spots, and release details of crime spots to taxi stations and unions at the beginning of each month,' union director Li Wing-sang said. 'However, because of a lack of resources, police say they will not be able to set up a hotline for taxi drivers.' Detective Senior Inspector Henry Chiang Kwok-wah of the Crime Prevention Bureau said roadblocks would be set up in crime black spots. On their part, 'taxi drivers should try to keep in contact with and give their location to the taxi station when they are in remote areas,' he said.
