Police are searching for someone who punched a man in the face following an argument over religion on the subway.

Two men were riding a northbound yellow line train at Court Street when they got into a disagreement over differing religions shortly before 9:30 a.m. last Sunday, police said.

As the train pulled into the 14th Street-Union Square station, one of the men stood up from his seat and punched the 40-year-old victim in the face when the train doors opened. The suspect then fled the scene.

The victim sustained an abrasion and a bruise to his right eye, police said.

The suspect was last seen wearing dark blue jeans and a green jacket. He is described as 6 feet tall with brown short hair.

The investigating is ongoing by NYPD's Hate Crimes Task Force.

Anyone with information regarding the incident should call the NYPD's Crime Stoppers Hotline at 1-800-577-TIPS.
