Macau police are to go hi-tech in the fight against crime by installing satellite tracking devices in patrol cars and fibre-optic security links with banks and shops. Superintendent-general Jose Proenca Branco - who commands the 3,200-strong Public Security Police - said the gadgetry was needed to combat violent crime. He said the measures would be implemented over the next few months. Mr Branco said initially 15 cars and five vehicles from a special investigation unit would be equipped with satellite global positioning devices. These would allow police headquarters to locate cars on an electronic map. The fibre-optic cable system, linking key banks and jewellery shops and other stores in the next few months, would allow police to receive live footage of hold-ups as opposed to relying on conventional alarms. Information on suspects and unsolved crimes will be posted on the Internet. The Public Security Police is the major law enforcement agency along with the 1,100-member Marine and Customs Police and the Judicial Police - a 300-member unit of detectives specialising in serious crime. Chief Executive Edmund Ho Hau-wah has said he plans to merge the Public Security Police and the Judicial Police to streamline crime-fighting, but has given no date.
