Police in New York City are investigating after several people were caught on surveillance video this week going into the sewer via a manhole and emerging hours later.
"Earlier today, authorities conducted a thorough investigation following reports of unauthorized individuals inside the sewer system on McDonald Avenue," the NYPD said on social media. "The NYPD and other agencies have completed their sweep, confirming the area is safe and free of hazards."
The people Department of Environmental Protection also did its own inspection, telling Fox News Digital: "DEP has inspected the sewer infrastructure at this location and found no damage to the system."
The spokesperson warned, "Entering the sewer system is both illegal and extremely dangerous. Sewers can contain numerous hazards, including noxious and potentially deadly gases, unstable surfaces, flooding risks, and confined spaces. For these reasons, members of the public should never enter a pipe, drain, catch basin, manhole, or outfall."
Fox News Digital has reached out to the NYPD for comment.
