Many residents in the northeast area of Carlisle Borough noticed police activity along E Louther St and N East St early Thursday morning.  As part of an ongoing drug investigation conducted by the PA State Police, Cumberland County Drug Task Force, and Carlisle Police, a search warrant had been obtained for a residence in the area.  That search warrant was executed yesterday morning and due to the nature of the investigation, it was accomplished with a significant police presence.  The entire search warrant detail was safely accomplished and two individuals were arrested.  Since the investigation is ongoing, no further information will be released at this time.  We wanted citizens in the area to know that their complaints of drug activity are heard and are being taken seriously.
