An argument on an uptown 6 train escalated into a slashing early this morning.

According to police, the attack took place at 3:10 a.m. Tuesday morning, and the victim's ring and middle fingers were sliced open as he attempted to grab the other man's knife.

Police say the slashing victim, a 40-year-old man, got off the train at Grand Central and sought help with NYPD officers at the station. His attacker remained on the 6 train. A police spokesperson confirmed that the man was taken to Bellevue Hospital.

Investigators have no description of the slasher other than "male." No arrests have been made and an investigation is ongoing. Earlier this year, an elderly woman was slashed on a 6 train near Bleecker Street by a man wielding an unknown object. The city has insisted that there is not an increasing trend in slashing attacks, but that hasn't stopped the NYPD from ordering 3,000 new pairs of slash-resistant gloves.
