NEW YORK (PIX11) — Random subway attacks have commuters in New York City worried.

A trip on the B train sent a 27-year-old man to the hospital with stab wounds after police say a man armed with a pocket knife attacked. The victim was heading into Midtown Manhattan around 2:45 a.m. when the attacker harassed him and then stabbed him as the train pulled into the Rockefeller Center station.

Over in Brooklyn, a 64-year-old man was beaten with a rock at a subway station. He was knocked unconscious during the attack.

Some people feel stuck taking the train with the crime because they can’t afford other forms of commuting.
