Deputies were searching an area near a Chase Bank Thursday afternoon in the Foothill Ranch area where a shot was fired during an armed robbery, authorities said.
Deputies responded to the south Orange County bank at about noon after a report of an armed robbery in progress. One shot was fired during the robbery, but it was not immediately clear whether the robber or a security guard fired the round.
No injuries were reported.
A detailed description of the robber, who left the bank, was not available. Authorities were searching a nature area near the bank with weapons drawn and at least one K-9 unit.
