New York City Sewer Intrusions Spark Safety Warnings and Motive Debate

Recent Unauthorized Sewer Incursions
Since May 5, 2026, surveillance footage has captured three separate groups entering New York City’s sewer system via manhole covers in Astoria, Queens, and later emerging in Brooklyn neighborhoods such as Gravesend and Williamsburg. The participants, equipped with headlamps, waterproof waders and tools, spent up to three hours underground before resurfacing. No injuries or arrests have been reported.
Background & Context
New York’s 7,400-mile (12,000-km) sewer network includes 6-foot-wide mains dating to the 19th century. The tunnels have attracted explorers and treasure seekers. In 2015, three DEP workers were charged after a four-hour search for “gold, jewelry and guns.” A trio was arrested in April 2025, saying they intended to sell recovered valuables. These cases show a pattern of illicit foraging.
Official Statements & Responses
A Department of Environmental Protection spokesperson warned that sewers contain “noxious and potentially deadly gases, unstable surfaces, flooding risks, and confined spaces,” stressing that entry is illegal and extremely dangerous. The NYPD confirmed an ongoing investigation with no injuries or arrests. Senior law-enforcement officials said the leading hypothesis is that the group is “scouring the system for valuables that get into the sewage.”
Criticism & Opposition
NYU engineering professor Magued Iskander argued that “there must be a reason beyond mere thrill to enter a dirty place like a sewer.” Retired NYPD detective David Sarni warned that the tunnels could be exploited for harmful purposes, citing gas and electrical lines. These views highlight concerns that curiosity-driven exploration may mask criminal intent.
Conflicting Reports & Gaps
Former urban explorer Steve Duncan says his forays are motivated by curiosity and a desire to experience the city differently, while law-enforcement sources describe the recent entrants as treasure hunters. It remains unclear whether a single coordinated group is responsible for all three incidents, and no forensic evidence has linked the participants to criminal activity.

- “They’re all over the place, crawling on walls, dropping down on you,” — Steve Duncan, former urban explorer
- “I knew they were up to no good,” — Aki Jakupovic, auto-repair shop owner
- “They could be electrocuted, they could be overcome, there’s gas lines down there, there’s electrical lines down there.” — John Monaghan, retired NYPD Capt. and law-enforcement analyst
- “Entering the sewer system is both illegal and extremely dangerous,” — Department of Environmental Protection spokesperson
Implications and Next Steps
The incidents expose critical infrastructure to unauthorized access, raising risks of toxic gas exposure, electrocution, and retrieval of hazardous or illegal items. Authorities are reviewing footage, tracing vehicle movements, and interviewing witnesses. The DEP has reiterated its warning, and law-enforcement officials plan to increase monitoring of manhole sites to deter future illegal entries.
