15-year-old boy loses his arm while subway surfing in Queens

A 15-year-old boy lost his arm while he was reportedly subway surfing in Queens on Monday.

The 15-year-old boy and three of his friends were attempting to subway surf at around 10:30 a.m. local time on Monday near the Roosevelt Avenue Station.

While the boy was trying to climb to the top of the train, he lost his balance and fell to the tracks. A moving R train ran over his arm, severing it, according to police reports.

The boy’s left arm was detached “from the elbow down.” His arm was later found under the train, according to a subway worker.

Paramedics rushed the boy to Bellevue Hospital, where he remains in stable condition.

“We know he was subway surfing on the outside of the car,” a transit worker at the station told The New York Post. “Usually when you’re subway surfing, you have to get off the train before the tunnel. He must’ve miss that point.”

The incident paused all incoming traffic to the station for more than an hour as police conducted an investigation.

Despite gaining popularity on social media, MTA officials have warned people against the dangerous trend of subway surfing.

"They just don't understand the meaning of life. That's what the problem is with a lot of these young people who are doing this kind of moronic, ridiculous thing," said Everett Jennings, of Rego Park. 

In June, another 15-year-old was left in critical condition after hitting his head while riding on top of a 7 train in Queens. The boy was found unconscious on the roof of the train car.
