Narrative:

On departure roll on 34L; at about 110 KIAS; den tower canceled our take off clearance after they detected a vehicle on the runway. They detected this through their ground radar; and it indicated a vehicle entering the runway at; I believe; taxiway wc. I aborted the takeoff and cleared the runway joining the eastbound parallel and held short of D1 taxiway. We told the passengers to remain seated; and shutdown our engines. Airport operations first showed; then the fire department. The fire department chocked our nose gear; so we could release our brakes. They did their inspection and everything checked out okay. While all this was happening I also communicated with flight dispatch; informed them of the incident and got maintenance control in the loop. They dispatched a team to inspect my tires; and eventually towed me in. Hottest brake temp was about 710 degrees. My first officer talked to tower while I was communicating with others and found out the vehicle incident was a false alarm. I'm sure there were things I could have done better; but overall the incident worked out well with the help I got from all parties involved.
