Detectives arrested a Bronx man who allegedly sucker-punched a 68-year-old man on board a train in Tribeca over the weekend and left the victim critically injured.
Police said the random attack took place at 2:40 p.m. on March 19 on board a Bronx-bound 1 train at the Franklin Street station.
According to law enforcement sources, the suspect — identified as Marc Mathieu, 36, of Bronx Boulevard — allegedly approached the 68-year-old man and, without any warning or provocation, punched the victim on the right side of his forehead.
Following the sucker punch, cops said, Mathieu alleged fled out of the station on foot in an unknown direction.
Officers from the 1st Precinct and NYPD Transit District 2 responded to the incident. EMS units rushed the man to NewYork-Presbyterian Lower Manhattan Hospital, where he was listed in critical but stable condition with injuries to his head.
Mathieu was arrested Sunday night and charged with assault.
