Authorities apprehended a suspect on Sunday in connection with an altercation at Penn Station that resulted in the death of a subway passenger, according to sources.

The individual was detained 18 hours after a confrontation with a 55-year-old man on the downtown C/E subway platform at 34th St-Penn Station on Saturday night, as reported by sources.

The medical examiner’s office has yet to determine the official cause of death. Consequently, the charges the suspect may face remain uncertain at this time.

Sources indicate that the incident began when the victim accidentally bumped into the suspect, escalating into a verbal dispute.

According to reports, the suspect struck the man in the face before fleeing the scene.

Police discovered the victim unconscious and unresponsive at the station shortly before 7 p.m., officials confirmed.

EMS rushed the man to Lenox Hill Hospital, where he was later pronounced dead, according to authorities.

Police said that the investigation was still ongoing and that there have been no arrests.”
