Heart-warming video has emerged of a stranger on a Brooklyn-bound train who literally gave the shirt off his own back to a half-naked homeless man.
The stranger, only known as Jay, is seen approaching the shirtless man on the train around 10pm on Friday (local time), according to New York Daily News.
Temperatures in New York at the time were near freezing, and the homeless man "looked sick", a bystander told the paper.
It's believed the Good Samaritan took the man to the hospital shortly after the video was taken.
The video has received more than 10 million views since it was uploaded on Saturday.
