A new cellphone video obtained by The Post shows a security guard stabbing another man in the face during a bloody brawl outside Penn Station — while an NYPD officer looks on.
The footage shows guard Walter Miller, 58, on the ground grabbing the unidentified victim by the hair while blood drips from the man’s face.
Miller is seen cutting the man’s face during the scuffle, while the victim tries to fend him off.
“Let ’em fight,” a man is heard saying, while an officer is seen on a few occasions standing nearby and is heard on the police radio.
A sergeant is then seen grabbing the victim and dragging him away onto the sidewalk.
The footage, obtained by The Post on Wednesday, was shot around 2:45 p.m. on Friday outside 2 Pennsylvania Plaza.
