Surfers have been urged to keep their valuables secure following an increase in criminal activity at beachfront car parks at Middleton.
Hills Fleurieu Police are again pleading with the public to ensure they secure their vehicle keys after another car was stolen yesterday.
Between 11am and 2pm on Wednesday September 18, a white VW Transporter van was stolen from Padman Crescent, while the owner was surfing. Thieves gained access to the vehicle using the keys which were 'hidden' in the car.
Police have since recovered the vehicle, however the owners possessions and mobile phone were stolen from inside.
This is part of a series of similar events occurring in the area and police are urging the public to be vigilant and secure their vehicle keys appropriately.
Since late August, police have received numerous reports of theft of motor vehicles and property from the Ocean Parade car park.
According to police, stolen cars have been found in the vicinity, but phones, cash, surfboards and tools inside the vehicles have gone missing.
Police said most times offenders used the car keys to open the vehicle.
"The keys have been left by the owner on the tyre under the wheel arch or left with a towel on the beach whilst the victim/s went surfing," police said in a statement.
Along with the Ocean Parade offending, a vehicle was stolen from the Mill Terrace car park on Wednesday, September 11 and recovered two hours later, but with three mobile phones, two wallets and house keys missing.
"Police would like to remind members of the public to secure their keys appropriately to prevent this type of theft occurring," police said.
Members of the public can report any suspicious activity to police by calling the assistance line on 131 444.
