Videos have surfaced showing groups of men entering and emerging from sewer manholes in Brooklyn, New York City, specifically near McDonald Avenue and Colin Place in Flatbush, and near Heyward Street and Bedford Avenue in Williamsburg [1][2]. At least seven men were seen at the Flatbush location, while a similar group of eight individuals was observed in Williamsburg [1][3].
The incidents occurred late Thursday night into early Friday morning, with the Flatbush group emerging just after 2 a.m. and the Williamsburg group exiting around 3:40 a.m. [1][2].
The New York City Police Department (NYPD), including its Emergency Service Unit, along with the New York City Department of Environmental Protection (DEP), investigated both locations. They found no damage to the sewer infrastructure and determined there was no threat to public safety [2][4].

A senior law enforcement official indicated that investigators’ leading theory is that the individuals were searching underground for valuables that may have entered the sewer system [2][5].
No arrests have been made, and the investigation is ongoing [2][3].
