Groups of people have been observed entering and exiting New York City sewers via manholes at night in Brooklyn and Queens. Police investigated multiple incidents but found no damage, suggesting urban exploration or treasure hunting as possible motives, though residents express concerns about security.
The incidents raise concerns about the security of critical infrastructure and the potential for illicit activities, despite official assurances of no immediate threat.
Surveillance footage has captured multiple incidents of groups of men entering and exiting New York City's sewer system through manholes in the middle of the night over the past few weeks. These events have been particularly noted in Brooklyn, with specific sightings in Gravesend and Williamsburg, as well as in Queens, Astoria. The individuals are seen descending into the sewers with flashlights, tools, and protective gear, such as waders and boots, and resurfacing hours later. The New York Police Department (NYPD) has investigated these episodes, including deploying its Emergency Service Unit and Canine Unit for underground inspections. The Department of Environmental Protection also inspected the sewer equipment and reported no damage. Officials have publicly stated that there is no known threat to public safety and have floated the possibility that the individuals are urban explorers or treasure hunters. However, the coordinated nature of these nighttime activities in critical infrastructure has fueled suspicion and concern among residents, particularly in the context of the city's ongoing challenges with migration and security. The article notes that unauthorized entry into the sewer system is illegal and extremely dangerous due to potential hazards like toxic gases, flooding, and collapses. Despite the authorities' reassurances, the lack of swift arrests or escalation to federal agencies has led to speculation about reconnaissance, sabotage, or terrorism, with some residents feeling the official response prioritizes managing narratives over transparency and security. The NYC sewer system is described as dank, dangerous, and bug-filled, holding a vast network of pipes that carry wastewater and storm runoff beneath the city.
