What do you think they are doing down there? Secret tunnels? Something worse?

I knew I wasn't crazy when I filmed this back in 2022. I've had this video saved for years, but now that the NYPD is officially investigating identical incidents happening across Brooklyn, it's finally re-emerging. They aren't city workers, they only move in the dead of night, and they completely change their appearance the second they surface. What do you think they are doing down there? Secret tunnels? Something worse? Look closely at the loop and drop your theories below. #brooklyn #nyc #williamsburg #unexplained #creepy
