A man was stabbed in the back by a stranger while waiting for a subway on NYC’s Upper West Side — the second person attacked from behind with a blade in the city’s subway system this month, police said Saturday.
The 23-year-old was on the northbound No. 1 platform at 96th and Broadway around 7 p.m. Friday when he had an argument with another rider, according to police sources.
