SmartWater is being used by local police forces across the nation to ‘trap’ car thieves. The substance, which is forensically-encoded, enables stolen goods to be 'recognised' and recovered, as information concerning models is stored in a database.
It could be that such a system helps people pay for car insurance, as cover companies may choose to reduce costs as a result, viewing the area as safe. Drivers could also find that the system stops them from making claims in the first place, as criminals may be deterred by the scheme.
The unmarked cars are fitted with SmartWater spray system which the police will be able to identify on criminals’ clothing during the routine ultraviolet light checks officers perform after arrests. Signs warning of the tactic will be put up in the areas where the trap cars are parked, with officers confident the high-profile tactics will deter potential thieves from attempting to steal a car.
Senior police officers believe criminals fear SmartWater and avoid stealing anything they suspect is marked with it because they know it will forensically link them with the scene of the crime.
A spokesman for a local constabulary said: "We have been quite overt about the trap cars in vehicle crime hotspots. We also want to assure everyone that we constantly check criminals for SmartWater."
