A woman slashed a man across the face at a SEPTA station late Wednesday, police say.
He ended up with 20 stitches. She fled.
The slashing happened at the subway platform at Broad and Hunting Park just before midnight.
The victim, a 23-year-old, got into an argument with the woman and another man, according to investigators.
She had "a small cutting object" in her hand and cut the man across the face, police say.
The alleged slasher and other man took off on foot.
