He can be heard screaming in pain at the start of the video taken in Brent, north-west London, outside Kingsbury Tube station.
Police are seen tending to the victim as a witness films the horrific scene from behind glass in a nearby building.

The shooting tonight comes just hours after shots were fired outside a school in west London.
Armed police were dispatched shortly after 4pm today after witnesses reported hearing three gunshots outside the Kennet West Skills Centre.
No students were in the school but building contractors working inside the building at the time of the incident spoke of how they ducked for cover after hearing the gunshots.
In the earlier incident, a motorbike driver is said to have opened fire on a white Volvo on Kennet Road.
No arrests were made and the Metropolitan Police said it was too early to confirm whether the two incidents were related.
Scotland Yard Commissioner Cressida Dick claimed violence in the capital was waning, despite around 90 killings so far this year, compared with 118 in 2017.
She insisted there was far more bloodshed in major US cities, even though in February and March London overtook New York's murder rate for the first time.
She said the murder rate had slowed in London – adding that there have been 161 killings in New York this year, almost double that in the capital.
