A New York City teenager was fighting for his life Saturday after he was stabbed during a fight over an iPhone at a Bronx subway station.

The 19-year-old saw that his friend's pocket had been slashed and his smartphone stolen after the two fell asleep on the downtown 4 train, polices sources said.

He spotted a man who he thought looked suspicious and began brawling with him over the missing device, police sources added.

When the train stopped at the Fordham Road station at around 4:00am local time, the scuffle spilled out on to the platform and the man stabbed the teen repeatedly in the chest and face, cops said.

Paramedics rushed the victim to St. Barnabas Hospital, where he was listed in critical condition, authorities said.

No arrests have been made.
