The victim has been identified as 34-year-old Jose Velazco-Alvarado, the Los Angeles Times reported.
A man has died hours after he was stabbed during a dispute on a Los Angeles subway train.
Sheriff's Department Transit Detective Keith Schumaker told the Los Angeles Times there was a brief verbal exchange captured by a security camera on the Metro Red Line train near Hollywood on Monday morning, then the suspect pulled a weapon and lunged at the victim.
Sheriff's officials say the train stopped at the Vermont/Santa Monica Station and the victim was taken to LA County USC Medical Center, where he died about nine hours later.
The name of the victim, described as a man in his 30s, was not immediately released.
Authorities are looking for the suspect, who is described as 18 to 24 years old.
