A pregnant woman is in critical condition after she and another woman were stabbed on the subway Thursday evening in the Bronx.
Investigators say the victims got into an argument with 50-year-old Derrick Wilson on a northbound 2 train around 6:30 p.m.
When they got to the Prospect Avenue station in Melrose, Wilson allegedly pulled out a knife and stabbed the pregnant woman in the neck.
The other woman was stabbed in the arm.
Wilson ran off but he was stopped by good samaritans who held him until police arrived.
He is now facing multiple charges including attempted murder, assault and criminal weapons possession.
