According to the New York Post, a man was aboard the 6 train at the station and exited onto the platform at the 125th Street and Lexington Avenue station in Harlem at about 10 p.m. on June 28.

The New York Police Department released an image of the suspect, who was described as a Hispanic male standing about 6 feet tall and weighing roughly 190 pounds.

He is believed to be about 35 years old was was last seen sporting a “man bun” hairstyle.

The alleged assailant was wearing a beige T-shirt and dark pants at the time of the incident.

The suspect allegedly stabbed the 36-year-old victim in the mouth with a writing pen before robbing him of his personal possessions.

As NY1 reported, the suspect shouted racial slurs as he initiated the attack.

Reports indicate the man got away with the unidentified train rider’s cellphone and threw out additional unspecified belongings onto the adjacent tracks as he ran off.
