MONEY, laptops, iPods and sat navs were all found on display in cars by police on Tuesday - as well as many vehicles which were left unlocked.
The day of action was held as part of South Yorkshire Police's Operation Lockdown, which aims to combat car crime and educate motorists on the perils of leaving their valuables on show to would-be thieves.
A number of car parks were visited to check for vulnerable vehicles as well as offer crime prevention advice to the public.
DCI Chris Singleton said: "Police are working tirelessly to help combat vehicle crime, but we cannot tackle this issue on our own.
"A significant number of crimes can be avoided if motorists take some simple preventative measures to secure their car and keep items out of view."
Launched at the start of October, the operation has been a success with over 20 arrests in Barnsley alone.
