Raleigh police arrested one person they say broke into several cars during a concert Saturday night at the Coastal Credit Union Music Park at Walnut Creek.
Police told WRAL News at least one gun was reported stolen during the break-ins, and a possibility that more were stolen.
Officers also said the parking lots are closely monitored, even with drones. But they said it is nearly impossible to prevent break-ins from happening.
In July alone, Raleigh police told WRAL News officers investigated more than 50 car break-ins, including several at the music park during another concert where guns were stolen.
Police are urging people to lock their vehicles and not to leave firearms or valuable items inside.
