A subway rider who reached the end of the line on a C train didn't react well to a conductor trying to wake him up when the train reached its destination, punching the woman in the face, according to the NYPD.

Cops say that just before 11 p.m. last Friday, a C train pulled into Euclid Avenue, the last stop on the southbound train. When an MTA conductor, a 40-year-old woman, woke up the sleeping passenger, the man punched her in the face and then fled in an unknown direction.

The conductor was taken to Jamaica Hospital in stable condition.

The suspect in the attack is described as a man between the ages of 20 and 30, about 5'10" and 175 pounds, and was last seen wearing a red hat, black shorts, and black sneakers.
