State police are investigating a spate of thefts in Saltsburg, just over the border from Westmoreland County. Trooper Clifford Greenfield said items were taken overnight during the weekend. Unlocked vehicles were targeted in some of the thefts on Hemlock Way and Salt, Walnut and Washington streets. Police were looking at surveillance video to compile a list of stolen property, which includes cash, $3,000 worth of Milwaukee tools, a black mountain bicycle and a red Taotao ATV. Residents were advised to secure their vehicles and property and report suspicious activity. Greenfield said troopers do not believe the thefts are related to a stolen vehicle investigation spanning three counties, including Westmoreland. Police are still working to determine who was behind those thefts, which police believe are connected, he said.
