Another building site in Mosgiel has been targeted by tool thieves overnight.
More than $16,000 worth of tools have been stolen from building sites in Mosgiel this month.
Senior Sergeant Craig Dinnissen, of Dunedin, said there had been at least four burglaries since the start of the month in which tools were taken from unsecured building sites in the town.
The property targeted last night was next door to one of the earlier sites that were targeted.
The tools were previously taken from sites in Gladstone Rd South, Owhiro Ave and Glengarry Court.
They included power drills, paint sprayers, belt-sanders and heat-guns.
"We really implore people to start engraving their tools ... because that's a better deterrent and way of identifying the tools when we execute a search warrant,'' Snr Sgt Dinnissen said.
