A 2-year-old wolf named Neukgu spent nine days loose in the outskirts of Daejeon, South Korea’s fifth-largest city, after digging his way out of the O-World zoo on the morning of April 8. The escape triggered school closures, a search operation involving more than 300 people, and a wave of public anxiety that dominated national headlines for nearly two weeks. On April 17, a capture team tranquilized the animal near an expressway and brought him back. A veterinary exam afterward revealed a fish hook lodged in his stomach, a stark reminder of the hazards a wild predator faces when it wanders into a landscape shaped by people.
The escape and the search
The breakout was caught on the zoo’s own cameras. CCTV footage reviewed by O-World staff showed Neukgu digging through soil beneath a barrier at ground level, according to a zoo spokesperson who described the spot as a weak point in the enclosure’s perimeter. The Daejeon Fire Headquarters, which coordinated the emergency response, placed the escape at approximately 9:15 a.m. local time. O-World canceled its scheduled opening for the day.
Within hours, the search expanded well beyond the zoo grounds. A Daejeon fire official told AFP that more than 300 people, including firefighters, police officers, and zoo employees, fanned out across the wooded hills and semi-urban corridors surrounding O-World. Teams deployed drones and patrol vehicles. Loudspeaker announcements warned residents not to approach any animal resembling a wolf. A spokesperson for the Daejeon Metropolitan Office of Education confirmed to AFP that local schools were closed as a precaution, and several outdoor events were canceled or moved indoors.
Over the following days, Neukgu proved difficult to pin down. Residents reported sporadic sightings, but authorities said many tips turned out to be false alarms or misidentified dogs. The pattern suggested the wolf was largely nocturnal, sticking close to cover and avoiding people. Search teams gradually narrowed the likely area using fresh tracks and a cluster of more credible sightings near an expressway corridor south of the zoo.
On April 17, spotters located Neukgu in roadside vegetation near the expressway. A veterinary team accompanying the capture unit sedated the wolf with a tranquilizer dart, avoiding lethal force in a traffic-heavy area, according to city and zoo officials cited by the Associated Press.
A fish hook and a close call
The post-capture veterinary exam produced an unsettling finding. An X-ray revealed a 2.6-centimeter fish hook lodged in Neukgu’s stomach, along with a leaf and fish bones, according to details shared at a Daejeon metropolitan government press briefing. Veterinarians removed the hook using an endoscopic procedure. Officials said the wolf had likely swallowed discarded fishing waste while scavenging near a waterway or drainage channel during its time outside the zoo.
The hook had not perforated the stomach lining or intestines, but veterinarians noted that outcome was largely a matter of luck. A perforation could have caused internal infection or bleeding, potentially killing the animal before it was ever found. The discovery underscored a risk that is easy to overlook in urban wildlife incidents: even when an escaped animal avoids traffic and human confrontation, the ordinary debris of city life can be lethal.
Public response and official accountability
Daejeon Mayor Lee Jang-woo posted a public apology on social media after the capture, thanking residents for their patience and acknowledging the anxiety the escape had caused. The statement promised a review of zoo management practices. City officials also emphasized that no injuries to residents or the wolf had been reported during the nine-day ordeal.
But the reassurances did not fully satisfy public scrutiny. South Korean media and online commentators pressed for answers about how a wolf could dig out of a zoo enclosure in a metropolitan area of 1.5 million people. O-World has not released detailed information about the enclosure’s design, construction date, or maintenance history. No independent engineering assessment of the barrier has been made public, and zoo management has offered only general descriptions of the escape method. Without that information, it remains unclear whether the failure was caused by outdated infrastructure, a maintenance lapse, or a flaw that no one anticipated.
There is also a small but notable discrepancy in official accounts of what happened to Neukgu after capture. Yonhap reported that city officials said the wolf was returned to its enclosure. The Associated Press, however, quoted the zoo director as saying Neukgu would be placed in a separate enclosure. Whether those descriptions refer to the same subdivided space or to genuinely different housing arrangements has not been clarified, leaving a gap in the public record about how the zoo is handling immediate containment.
Unanswered questions about zoo safety
The Neukgu incident has drawn attention to broader questions about how South Korea regulates its zoos. The country’s Animal Garden Act, revised in recent years to tighten licensing and welfare requirements, sets baseline standards for enclosure design and animal care. But enforcement has been uneven, and animal welfare groups have long argued that many facilities, particularly older municipal zoos, operate with infrastructure that predates current guidelines.
O-World, which is managed by the city of Daejeon, has not said whether its wolf enclosure met the most recent national standards or when it was last inspected by an outside authority. No wildlife or environmental agency has publicly assessed whether Neukgu posed risks to native species during his time outside the zoo, or whether the wolf was exposed to pollutants, treated roadkill, or other hazards common in urban-fringe landscapes.
Authorities have also not released detailed logs of emergency calls or verified sightings from the nine-day search. The absence of reported attacks suggests the risk to residents remained low, but without systematic data, it is difficult to know how close the city came to a more dangerous outcome.
As of late April 2026, Daejeon officials have said a formal review of O-World’s animal management protocols is underway, though no timeline for its completion has been announced. For now, Neukgu is back behind a barrier. Whether that barrier, or the system that failed to keep it intact, will be meaningfully improved remains an open question.
