Four alleged gang members were arrested in Napa late Saturday night after police spotted them fleeing the scene of a reported fight and found a dangerous weapon in their car, according to Napa police. Officers responded around 11:45 p.m. Saturday to a report of a fight in the 800 block of Laguna Street and spotted a car fleeing the area with its lights off, police said. Police said an officer stopped the car near the intersection of Jacob Court and Carriage Place and saw that its occupants were known gang members. A search of the vehicle revealed a metal club stowed in the car's glove compartment along with other evidence of gang affiliation, police said. Police said two of the car's occupants, are on probation with the Napa County Sheriff's Office, and that one, 22-year-old Napa man Antonio Estanislao Juarez, allegedly gave police a fake name. Officers arrested Juarez, 19-year-old Victor Ortega and Jesus Juan Avalos, 20, who was driving the car, as well as a 17-year-old Napa boy on suspicion of participation in a criminal street gang and for alleged weapon possession. Avalos, Juarez and Ortega were booked into the Napa County Detention Center and the 17-year-old was taken to Juvenile Hall.
