A feisty Harlem woman turned the tables on three subway muggers, chasing down two of the thugs while snatching back her purse - because it had her green card in it, cops said yesterday.

Marie Conde, 26, was riding a downtown 3 train at 5:30 a.m. Sunday and had briefly dozed off when three punks confronted her as it pulled into the 72nd Street station.

"I opened my eyes, and one of them punched me in the right eye," the French-speaking Guinean immigrant told The Post through an interpreter.
