A teenage boy has died after attempting a dangerous social media trend of "subway surfing".
The 14-year-old boy fell from a train in Queens, New York City, and suffered a fatal head injury.
He was taken to hospital where he later died.
His identity and whether he was alone at the time are unknown.

The teenagers, both 14, were knocked off an L train while subway surfing in Brooklyn.
They ended up underneath the train and suffered "serious trauma to their bodies", NYPD Chief of Transit Michael Kemper said.
According to the MTA, there were 52 reports of people riding outside of subway cars in the city in February and 58 in January, the most recent stats available for 2023.

TikTok expressed condolences and stated that they remove such content when found.

"This dangerous activity predates our platform, and we strictly remove such content if we see it on TikTok.
"More than 40,000 safety professionals are dedicated to keeping our community safe and work diligently to remove harmful content when found."
The Metropolitan Transportation Authority sent a statement from NYC Transit President Richard Davey, to CBS News.

"And if you are a parent and you think your child is engaged in subway surfing, riding between cars, please tell them it is not a game. Lives are lost. Lives are lost."
