New York City police are investigating a recent video showing people climbing out of a manhole and emerging from the city’s sewer system. ABC News and The Guardian both report that the episode is part of a continuing series of similar incidents that have occurred overnight in Manhattan.

The Guardian says a social media clip posted to TikTok shows three people emerging in sequence around 4:19 a.m. on 18 August near Madison Square Garden. The individuals are reported to be wearing headlamps and black overalls. ABC News describes the broader pattern as occurring in the middle of the night, without focusing on the exact details of this latest video.

Authorities’ response is consistent across outlets: the NYPD is treating the new footage as an active matter for investigation and checks around the sewer access points. The differing coverage centers mainly on descriptive specifics of the video—such as location and clothing—rather than on the underlying allegation that people used a manhole to enter and exit the sewer system.
