The City of Anderson’s Problem Oriented Policing Unit did another one of their pro-active enforcement details Thursday. The APD unit had help from Shasta County Probation, the Marshal’s Office and the Department of Homeland Security. A total of 30 people were contacted and ten of them were arrested. 12 probation and parole searches were done and three children were taken into the custody of Shasta County Child and Family Services. Most of the ten arrests were for probation violations and warrants.
