LAS VEGAS (AP) — Authorities say they have found what looks like a hand grenade inside a knapsack dropped by a gunman at a Las Vegas-area Walmart.
A Las Vegas fire spokesman says the knapsack was secured by a bomb-squad, but investigators weren't immediately able to determine Sunday if the object inside was a real or fake hand grenade.
Metro Lt. Steve Herpolsheimer told the Las Vegas Sun the incident began Saturday when the Henderson store refused to cash a man's check. A guard followed him outside where the man allegedly struck the guard with a gun and fled, dropping the bag.
The store was evacuated and closed for about two hours. The guard wasn't hurt.
Las Vegas police say the suspect remains at large.
A week earlier, a disgruntled Walmart employee in Reno shot and wounded three of his managers before surrendering.
Las Vegas fire spokesman Tim Szymanski told The Associated Press that his department's investigators were busy working another case Sunday and won't determine until Monday whether the grenade is genuine or an inert souvenir without explosive components.
