Sydney Trains has begun trialling a new security device designed to catch vandals in the act. The electronic chemical sensor, known as the Mousetrap, detects vapour given off by spray paint and alerts Police Transport Command (PTC). A number of trains have already been equipped with the sensors, leading to the arrest of more than 30 offenders to date. Mousetrap, which can even detect vandals using marker pens, works alongside traditional CCTV to record and catch offenders. [From Richard Buckby]
