A 59-year-old MTA conductor was slashed in the neck Thursday morning while on an A train pulling into the Rockaway Avenue station.
Authorities say the attack took place just before 4 a.m. as Alton Scott looked out of the window to check for passengers.
He called for help over the PA system, prompting several people to come to his aid.
One of those individuals was a doctor, according to police. Scott says the doctor saved his live.
The conductor was hospitalized following the incident and later released to recover at his home.
Police say they are searching for the attacker. The MTA also says the train may experience delays.
Transit crime is up by 19% in the northern part of Brooklyn, according to the latest data from the NYPD.
Just last week, Mayor Eric Adams announced officers would be moving to
12-hour shifts to combat subway crime.
