By Sunday afternoon, officers with the Napa Police Department have issued about 40 warnings to people illegally selling tickets outside BottleRock, Lt. Debbie Peecook said.
Scalpers were given a warning on first contact and had their tickets confiscated by authorities. A second contact would have resulted in a citation, but as of Sunday afternoon, none had been issued.
Uniformed officers, security guards and undercover officers all worked to spot out the scalpers that were within a few blocks of the Napa Valley Expo gates. Peecook said most were from out of town and were told to leave upon contact.
