A “loud bang” caused by breaking glass at MGM Grand sent tourists on the Strip into a panic Saturday night and set social media ablaze with false reports of an active shooter.

At about 10 p.m., a person “had broken a window” in the casino’s valet area, Metropolitan Police Department Capt. Branden Clarkson said at briefing shortly after midnight. “It caused a loud bang, there was a subsequent panic, thinking it was possible gunfire given the nature of what’s been happening across the nation.”

He said a person was “immediately” taken into custody and faces a misdemeanor charge of destruction of property.
