Narrative:

On takeoff roll at V1 (152 KTS) tower says 'cancel takeoff clearance, unauthorized vehicle crossing downfield.' as we rotated we were able to see the vehicle now across the runway near the end. On departure control, they said it was a local problem and were filing a report to airport security on it. No reflection on our operation!
