A 31-year-old man was slashed inside the Times Square subway station Tuesday night in the latest bout of violence within the Big Apple’s mass transit system.

The victim was slashed in the leg by another man during a fight inside the station’s mezzanine near the shuttle train to Grand Central just before 11 p.m., police said.

Dramatic video posted to Twitter shows officers treating the injured and bleeding man on the subway platform, with a trail of blood behind him.

He was taken to Bellevue Hospital in stable condition.

His attacker fled the station towards Grand Central Station, according to the NYPD.

It wasn’t immediately clear what sparked the bloody feud.
