Police say Donny Ubiera, 32, of Queens was arrested Saturday night and is facing two charges of attempted murder, two charges of assault, and two charges of criminal possession of a weapon in connection to the pair of seemingly unprovoked attacks.
Authorities say that on Friday, at around 8:40 a.m., a 62-year-old man was riding a southbound 7 train when he was approached by the suspect. The suspect displayed a large knife and proceeded to slash the victim several times, causing lacerations to the victim's face and hand.
The suspect got off the train at the Queensboro Plaza station and fled toward Queens Plaza North.
The victim was taken to NYC Health & Hospitals/Elmhurst in stable condition where he received multiple stitches for his injuries.
Almost 24 hours later, the suspect struck again at the 74th Street-Broadway train station, stabbing a 55-year-old man that was waiting for a northbound 7 train in the neck.
The suspect ran away after the stabbing and the victim was taken to NYC Health & Hospitals/Elmhurst in critical but stable condition.
A knife was recovered at the scene by police.
