A group of eight pranksters were seen riding the roof of a subway train across New York's famous Williamsburg bridge.
Footage showing up to eight individuals in black clothing riding the top of the Metro J-Train as it emerged on the overpass from Manhattan's Lower East to Willaimsburg's Marcy Avenue Station.
The individuals were seen running the length of the train and leaping between carriages, filming themselves on mobile phones.
A clip filmed from Williamsburg on Friday gained viral attention and six million views, asking if anyone else had seen the daredevils.
"These people just came over the Williamsburg bridge on top of the train," tweeted @GooseyMane from his highrise view in disbelief.
Quickly others confirmed the sightings including passengers and one reply from someone claiming to have been one of those on top of the train.
