Authorities say they know who is behind two knife attacks within the span of 24 hours on the same subway line in Queens that sent two people to the hospital.
After the second attack Saturday morning, the NYPD released photos of Donny Ubiera, 32, in hopes of getting help from the public in tracking down the alleged knife assailant.
The Queens man is accused of first stabbing a 62-year-old man onboard a southbound 7 train around 8:30 a.m. Friday, during the morning commuter rush. Police said the victim was slashed in the face and hand, requiring several stitches at the hospital.
Ubiera allegedly fled the train at Queensboro Plaza and was seen wearing a black and gold button shirt with black shorts.
