One man was arrested and police are seeking information about another following a report of an armed robbery on Hagen Road near Silverado Trail during the BottleRock music festival on Saturday, according to Napa Police.
The two suspects had met the victims to make a jewelry purchase, police said. Police said that they don't when the suspects decided to rob the victims.
The suspects fled in a vehicle, but were located by a Napa County Sheriff's deputy in the area of Hagen Road and First Street.
As the deputy pursued the vehicle, it continued to the Napa Valley Expo, where BottleRock's second day of concerts was being held. Once at the festival, police said, the suspects exited the vehicle and continued to flee on foot.
One man, identified as William Frederico Carter, 27, of San Francisco, entered the fairgrounds via a gate on Third Street and was immediately arrested.
Carter was booked at the Napa County jail.
Police were unable to locate the other suspect as of Sunday morning. He was described as being a Hispanic man in his late 20s to early 30s with dark curly hair, wearing a black T-shirt and jeans. He was last seen outside the Expo in the area of Silverado Trail and Third Street.
Police said the charges include armed robbery, use of a firearm while committing a felony, evading, being a prohibited person in possession of a firearm and ammunition, assault with a deadly weapon, committing a felony while out on bail, and carrying a loaded and concealable firearm in a vehicle.
The entrance gates to BottleRock were temporarily secured during the incident, delaying some festivalgoers trying to enter the Expo, according to police.
The victims were not physically harmed, police reported.
