About 40 people were arrested today after sheriff’s deputies raided a cockfight this afternoon, a spokeswoman for the Napa County Sheriff’s Office said. At around 4:15 p.m., police responded to reports of cockfighting with drugs and firearms involved in the 1400 block of American Canyon Road, Capt. Tracey Stuart said. When sheriff’s deputies arrived, about 40 people were cited and released for being a spectator at a cockfight, she said. Deputies are still at the scene interviewing suspects and collecting evidence. They have found at least two dead birds so far, she said. The California Highway Patrol had to briefly shut down American Canyon Road because there were so many people fleeing the scene when deputies arrived, Stewart said.
