A hotheaded teen slashed a man in the face and then pushed him onto the tracks during a squabble in a Manhattan subway station, police said Wednesday.

Tyrik Webster, 18, was walking on the A train platform at Broadway and John Street in the Financial District around 12:30 a.m. Tuesday when he allegedly bumped into a woman, police said.

A 31-year-old man began arguing with Webster about the alleged altercation, prompting the teen to pull out a green razor blade and slash him on the right side of his face, cops said.

Webster then pushed the victim onto the tracks and fled, authorities said.

He was busted shortly thereafter on the corner of Broadway and John Street and was charged with criminal possession of a weapon and assault.
