A Walmart in Garden Grove was evacuated Sunday, Oct. 29, after reports of an armed man in the store, but no weapon or suspect was found, authorities said.

Two men were arguing outside the store at 11822 Gilbert St. around 5:45 p.m. when one thought he saw the other run off with a gun, said Garden Grove police Lt. Jeff Nightengale.

He told a Walmart employee the man may have run inside the store, prompting the evacuation, Nightengale said.

Police responded, along with Anaheim an police K-9 unit and an Orange County Sheriff’s Department helicopter, and did not find the man or a weapon.

No one was injured and the store was reopened several hours later, Nightengale said.
