A man armed with a machete, a pickaxe and what police described as a weapon resembling a hammer tried to rob the jewelry counter inside a Costco on Woodruff Road in Greenville, and shoppers did not wait for police to intervene. Customers physically detained him until officers arrived, according to police, ending the attempted robbery.
The Greenville Police Department confirmed a man was arrested in connection with the armed robbery attempt at the Costco store, as reported by Fox Carolina. Police responded to the store after callers reported the attempted robbery of the jewelry counter, and officers said the suspect was equipped with a machete and pickaxe. He also had a weapon that appeared to be a hammer, according to police, and at some point he mentioned that he had a gun, though details remained limited at the time of the outlet’s reporting.
Fox Carolina crews were en route to the scene as the story developed, while available details remained limited. At the time of reporting, the available account did not include additional details about the arrest or formal charges.
How Customers Were Legally Allowed to Step In
The fact that ordinary shoppers held the man down until police showed up raises the question of what legal footing they were on. South Carolina courts have eliminated general common-law citizen’s arrest rights, meaning the only authority available to private individuals comes from statute. Under South Carolina Code § 17-13-10, private citizens are granted the authority to make an arrest if a felony or larceny is committed in their view or presence, according to Federal State Law — but the source does not determine whether that statute applied to the Costco customers’ intervention.
If convicted, the suspect faces steep consequences. Armed robbery in South Carolina is a felony under South Carolina Code § 16-11-330, punishable by 10 to 30 years in prison, and defendants must serve at least 85% of that sentence before becoming eligible for parole, according to Adams & Bischoff. The statute covers robbery committed while armed with a deadly weapon or while representing that one is armed; whether the items described in this case meet that standard is not determined here.
A Recurring Target Nationwide
Costco jewelry counters have proven a recurring target for smash-and-grab attempts using blunt or bladed tools across the country. In May 2020, two suspects used a mallet to smash display cases at a Costco jewelry counter in Tracy, California, making off with $150,000 worth of jewelry before their arrest, as reported by CBS News. In January 2019, two men armed with an axe and a sledgehammer smashed a jewelry case at a Commerce Township, Michigan Costco before fleeing store personnel, according to ClickOnDetroit. In other reported incidents, suspects used tools to smash Costco jewelry cases. The Greenville incident involved a machete, pickaxe and hammer-like tool, while police also reported that the suspect mentioned a firearm.
Woodruff Road’s High-Traffic, High-Scrutiny Corridor
The Costco sits along Woodruff Road. The available material does not provide details of a January crash response on Woodruff Road. The City of Greenville also listed a proposed annexation and rezoning item in its newsroom material, according to the City of Greenville.
The armed robbery attempt also comes amid discussion of crime in Greenville this month. The article references an unverified gunfire report. That same report noted Police Chief J.H. Thompson had told City Council that overall crime in Greenville fell more than 20% in the first quarter of 2026 compared to the same period the year before, a statistic that stands in contrast to the string of high-profile armed incidents making headlines. It remains unclear whether Costco or Greenville police will issue any additional guidance to customers about intervening in armed situations following the Woodruff Road arrest.
