A concern group has proposed that location-tracking technology be used to help crime victims in country parks, after another hiker was robbed yesterday. The 64-year-old hiker, surnamed Ng, was robbed by a man armed with an axe while walking along Hammer Hill Road, near King Lai Court, Wong Tai Sin, at 10.30am. Mr Ng lost a mobile phone and $20 in cash. He reported the case to the police after the robber escaped but no one has been arrested. Calling for the use of a tracking system yesterday, the group Civilian Turn-Up said the technology required a specially made SIM card to be inserted into mobile phones. The card is linked to a telecommunication system and sends data about a hiker's location via the mobile phone to an operator every 15 minutes. If no signal is received for more than one hour, the system generates a warning to the operator. Users can request the operator to contact their families or the police when this occurs. The group tested the system on May 23, during a hike involving more than 1,000 participants in Lion Rock Country Park, a robbery black spot. Releasing the results of its survey on hiking safety, Civilian Turn-up said about 62 per cent of the 1,051 hikers interviewed found safety measures and emergency phone booths along hiking paths to be inadequate. 'The result shows that the government should improve the telecommunication system in country parks, so that hikers can use their mobile phones,' group chairman Hugo Lam Man-fai said. 'We believe the location-tracking technology is the key to robbery problems in these remote areas. 'If a hiker goes missing, police can conduct a search according to these data. 'The search area is at least narrowed down. Police can look for hikers who might be robbed or injured in the area where the contact was lost.' The group urged the government to permit the installation of receivers in country parks to strengthen the telecommunication network. 'The system does not and will not destroy the natural environment and beauty of nature as the signal receivers are only small boxes,' Mr Lam said. Civilian Turn-up will hold another hike in November, when 100 participants will be invited to take part in the second trial of the location-tracking system.
