Police have asked people with home security cameras to help them stop thieves who are breaking into unlocked cars.
Officers from the North West neighbourhood police team (NPT) are investigating a number of thefts from cars that took place in Horbury and South Ossett.
They all took place between Sunday, March 17, and Monday, March 18.
Cars parked on Southwell Lane, Jacobs Court, Industrial Street, Jenkin Lane and Quarry Hill were targeted.
Police believe all the cars were not locked.
Insp Jo Mercer, of the North West NPT, said: “Residents can assist us by ensuring their vehicles are locked and secure and that valuable items are removed from display.
“This type of crime in this area is unusual but it is clear there are opportunist thieves out and about.
“We have secured CCTV in the relevant areas but if anyone has any footage we are unaware of or any information at all regarding the thefts please contact us.”
The NPT need footage taken from personal security cameras on or around the streets affected between 11pm on Sunday, March 17, and 6am on Monday, March 18.
Insp Mercer also urged people who have not reported thefts from their cars to come forward.
She said: “We advise all residents to make sure their cars are locked and secure at all times. Do not leave expensive satellite navigation systems, handbags or laptops on display. If you see someone acting suspiciously then please contact the NPT or Crimestoppers.”
The thefts have renewed the debate over CCTV cameras in Horbury.
It is the only town in the Wakefield without CCTV cameras.
For more than a decade residents, business owners and councillors have called for cameras to be installed to improve safety and help police trace criminals.
In 2010 Coun Graham Jesty, who represented the ward at that time, started a petition to lobby Wakefield Council to invest in CCTV for the town.
It was sparked by a number of thefts from shops, vandalism attacks and problems with anti-social behaviour.
The call for CCTV was backed by the Express’ Standing Up For Horbury campaign.
Hundreds of people signed the petition and calls for CCTV were also supported by the North West NPT officers and business owners.
But Wakefield Council said the scheme would cost too much of tax payers’ money to install - at a time when it was having to make cuts to meet tough budget constraints.
