Teen stabbed in leg on Brooklyn subway after argument with three men

A teenager was knifed in the leg on a Brooklyn subway Friday night, cops and law enforcement sources said.

The 17-year-old was on a D train headed for the Norwood-205 St. station in the Bronx when he got into an argument with three men, each armed with knives, the sources said.

Their quarrel came to a head when at least one of his adversaries stabbed him in the left leg at about 9:12 p.m. as the train rumbled into the Union St. station near 4th Ave. in Park Slope, cops said.

It was not immediately clear if the victim knew the trio.

The suspects, described as three black men detrained at the Union St. station and ran off in an unknown direction, police and the sources said.

Medics rushed the victim to NewYork-Presbyterian Brooklyn Methodist Hospital where he was listed in stable condition.

Cops have made no arrests. The investigation remained ongoing Friday night.
