The NYPD K-9 unit, FDNY, and Department of Environmental Protection showed up to the scene and investigated.

A spokesperson for the New York City Department of Environmental Protection confirmed that the sewers at both locations were inspected and deemed the infrastructure safe, but emphasized that entering the sewer system is both illegal and 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,” the spokesperson said in a statement.

Council Member Susan Zhuang commended the NYPD and DEP for their response to the incident and echoed the safety risk of entering the sewers.

“What happened in Gravesend and Bedford Avenue this week was dangerous, illegal, and cannot be dismissed. Our sewers contain deadly gases, unstable surfaces, and serious flooding risks, they are not a place anyone should ever enter,” said Zhuang in a statement.
