Brutal video obtained by The Post reveals how a gruesome, fatal subway surfing incident on the Williamsburg Bridge in Lower Manhattan unfolded.
The clip shows the 14-year-old boy and his 18-year-old pal on the top of the J train as it zoomed along in Lower Manhattan on its way to Brooklyn Friday – before one of them is struck in the head by a beam and falls all the way to the ground below.
The other boy appeared to crouch down to avoid the low beam, a police source said. He can then be seen falling onto the rails on his back.
The pair were found on the tracks, unconscious.
The 14-year-old boy was killed and the 18-year-old was gravely injured, cops said.
The older surfer, who turned 18 on Friday, was rushed to Bellevue Hospital in critical condition.
In October, a 12-year-old Brooklyn girl was killed in a similar subway surfing incident on the same span.
Zemfira Mukhtarov had frequently posted her death-defying adventures on TikTok before she was killed.
