A 24-year-old man is "fighting for his life" after being stabbed on a SI 74 bus this afternoon.

Police say the attack occurred around 1:45 p.m near Canal and Water Streets in the Stapleton section of Staten Island: The victim had been in a dispute over a seat when the assailant stabbed him multiple times in his hand and torso. The victim was described as being in "likely" to die condition by an NYPD spokeswoman.

A neighborhood resident told the Staten Island Advance, "I can believe it (that it was over a seat on the bus). The 74 is known for this. This is a scary thing to happen in the neighborhood. I have to take more precaution now."

The suspect, apparently in his 20s, fled by foot. The investigation is ongoing.
