On Tuesday, at about 3 a.m., the same man is suspected of attempting to rob another subway rider. The 37-year-old victim was asleep on a northbound 4 train when he felt a tug on his pants, cops said. He then awoke and saw the suspect standing over him holding a razor in his hand as his jean pocket was being cut. 

He tried to restrain the suspect and was punch in the face, according to police. The suspect then fled the train at the 51st Street stop before taking any property.

In addition to his red, flat top-style hair, police also described the suspect as black, 20 to 30 years old, 5 feet 11 inches to 6 feet tall, with a thin build.
