Shoppers are being allowed back into the Lake Havasu City Walmart store after police responded to reports of a man with a gun.
Police Lt. Kirk Cessna says officers got a report of a person in the bathroom area of the store with a gun, pointing it at people.
Officers on scene were seen responding with issued sidearms and AR-15 rifles to respond to the apparent weapon situation.
Officers arrived and evacuated the store, but they didn't find anyone with a weapon. The evacuation was lifted around 10:40 a.m.
Police are now investigating the call as a possible hoax, he said, and the department may request prosecution if the phone call turns out to be a prank.
