The department made national headlines on May 9, 1980, when five men armed with shotguns, an assault rifle, handguns, and an improvised explosive device robbed the Norco branch of Security Pacific Bank. Since dubbed the "Norco shootout", deputies responding to the bank robbery call, armed only with their pistols, confronted the perpetrators outside the bank and a prolonged gun battle and subsequent vehicle pursuit ensued. The aftermath of the incident left 33 patrol cars damaged or completely destroyed, one sheriff's helicopter shot down, three robbers imprisoned for life, two robbers dead, eight sheriff's deputies wounded, and one deputy killed in the line of duty.
