Police are appealing for those who use park and ride facilities or similar communal parking areas to make sure all valuables are removed before leaving their vehicles.
Superintendent Emma Bond said: “In recent weeks we have seen increased reports of thefts from vehicles at these parking facilities and while we are investigating those incidents and putting in place extra patrols, we are also asking drivers to take some personal responsibility.
“Opportunistic criminals will go for the quick win, so that means targeting the car that has a handbag or a tablet or even cash lying in plain view. Van drivers can be an easy target if thieves believe they can walk off with expensive tools so make sure you remove anything that is of value before leaving it for the day or overnight.
