BROOKLYN, NY— More than a dozen people climbed into Brooklyn's sewer system through manholes at two locations overnight, prompting a police investigation and a multi-agency search of the underground network.
At least seven people descended through a manhole near McDonald Avenue and Colin Place in Gravesend at about 11 p.m. Thursday, according to police. Witnesses later saw the group emerge around 2 a.m. Friday.
“Authorities conducted a thorough investigation following reports of unauthorized individuals inside the sewer system on McDonald Avenue,” the NYPD's 62nd Precinct said in a social media statement.“The NYPD and other agencies have completed their sweep, confirming the area is safe and free of hazards.”
Roughly three hours before the Gravesend group resurfaced, another eight people entered the sewer system through a manhole near Heyward Street and Bedford Avenue, about eight miles away, according to police. Authorities said the group climbed out shortly before 4 a.m. and left the area in a vehicle.
The incidents drew a response from the NYPD K-9 Unit, the FDNY and the New York City Department of Environmental Protection, which inspected both locations.
Investigators have not said why the groups entered the sewer system or whether the two incidents are connected.
Council Member Susan Zhuang praised the emergency response and warned against entering underground infrastructure.
“What happened in Gravesend and Bedford Avenue this week was dangerous, illegal, and cannot be dismissed," Zhuang said. "Our sewers contain deadly gases, unstable surfaces, and serious flooding risks, they are not a place anyone should ever enter."
Police continue to investigate both incidents.
