Police in New York City are asking for the public's help in identifying a suspect who slashed another man in the face when he tried to intervene in a fight aboard a Brooklyn subway train last week.

The assailant allegedly shouted, "Mind your own business!" before raking a sharp object across the 44-year-old victim's cheek, leaving a deep gash last Wednesday, the New York Daily News reported, citing police sources. The suspect reportedly then hopped out of the train as soon as the subway doors opened and ran away.

The New York City Police Department on Saturday first released photos and footage from surveillance video and asked for the public's help in identifying the person wanted in connection to the assault that occurred within the confines of the 79 Precinct/Transit District #30. As of midday Sunday, no arrest had been made.

It was reported to police that around 9:50 p.m. Wednesday, the victim intervened in a dispute between two men on board a southbound "C" train near the Clinton-Washington Avenue subway station.

The Brooklyn slashing reportedly unfolded 10 days after Jordan Neely, a 30-year-old homeless man who prosecutors say had been "making threats and scaring passengers" on the subway, died after Marine veteran Daniel Penny intervened and was captured on video placing him in choke hold inside the train car.
