An innovative technical device is keeping members of the public aware of car crime issues in their neighbourhood. Solar-powered talking signs are reminding motorists about leaving no valuables on display so that items are not stolen from vehicles. Police in Greater London will also be putting up ordinary signs alerting about car crime. A Southall Police statement said: "Reducing thefts from vehicles is a priority for us. A lot of car crime is random, and cars are broken into to steal anything on show."
