An accident on Harrison Street in Eureka shortly before 10 a.m. left two people trapped inside a car that had rolled onto its side, according to scanner traffic. Emergency responders have initiated a “full extrication,” the dispatcher said.

At least one lane of Harrison has been closed near the intersection with Buhne. We will update when we have more information.
