A Brooklyn subway rider repeatedly knifed an on-duty MTA conductor trying to empty a car after the train reached its last stop Tuesday, police said.
The unidentified assailant was sitting in a No. 4 train car at the Crown Heights-Utica Ave. stop at about 10:50 a.m. when the 64-year-old conductor walked through, telling passengers remaining on the train they had to step out onto the platform.
The suspect refused to leave, sparking an argument, police said.
He then flashed a knife and lunged at the MTA employee, stabbing him six to nine times in both the stomach and leg, said members of Transport Workers Union Local 100, which represents MTA conductors.
EMS rushed the conductor to Kings County Hospital where he remained in critical condition, union members said.
The stabber ran off and police were reviewing surveillance video, cops said. But 1010 WINS subsequently reported that a person of interest had been apprehended.
Cops could not immediately confirm that the attacker was in custody.
