Limestone Coast Police are investigating recent thefts of recyclable semi-precious and scrap metal from Bordertown and Keith.
Scrap metal was stolen from the rubbish dump at Bordertown between April 24-28.
Police believe the theft is likely linked to another theft at Keith between April 27 and May 8 of eight 20-metre lengths of copper cabling from a locked storage container.
The theft of copper, aluminium and brass is a widespread problem for public utilities and services, private companies, the building industry and scrap metal businesses.
Scrap metal can also pose a danger to thieves as well as cause significant damage to property.
Police urge the public to be on the look out and report any suspicious behaviour, day or night, to police. Contact the police assistance line on 131 444 immediately.
Scrap metal businesses are also reminded to be vigilant and keep good records of their business interactions in order to prevent opportunistic thieves from profiting from crime.
Anyone with information about scrap metal theft can report it anonymously to police via Crime Stoppers on 1800 333 000 or online at www.crimestopperssa.com.au
