A Brooklyn straphanger slashed another passenger after their pair collided onboard a train last week.
The violent attack occurred at approximately 5:23 p.m. on Aug. 29 aboard a Queens-bound A train near the Hoyt-Schermerhorn Streets station, police said.
Cops say a 31-year-old man entered a crowded train and accidentally bumped into the suspect. Becoming enraged, the perpetrator yelled something the victim did not understand before pulling a sharp object from his backpack.
Law enforcement sources said the brute then slashed the commuter across his face and left wrist as the train, then departed at the Hoyt-Schermerhorn stop before officers from the 84th Precinct and NYPD Transit District 30 could apprehend him.
The victim, meanwhile, was taken to Brookdale University Hospital Medic
