Police have released a sketch of the suspect wanted in connection with an attack on a man waiting for the train at the Tremont Avenue station last month.

Police say the suspect called the 21-year-old man a derogatory, anti-gay slur and then tried to swing a hammer at the victim. Police say the suspect eventually pushed the victim onto the train tracks.

Another person on the platform signaled to the conductor to stop before the man was hit. News 12 spoke with the victim's mother who says she hopes this helps catch the suspect.

The victim's mother told News 12 her son suffered a concussion, but that he is back home recovering now. She says she wishes there were cameras at the station so the suspect could be seen clearly.

The incident sparked outrage with Gov. Andrew Cuomo directing the State Police Hate Crimes Task Force to help the NYPD in its investigation.

Mayor Bill de Blasio also tweeting, "This is just reprehensible. Hate has no home in this city."

The victim's mother told News 12 her son is already back taking the subway to get to work even though he's still shaken up. She says he was actually about to walk home the night of the attack, but last minute decided to take the train.

She's glad they were able to spend Thanksgiving together, but hopes the suspect is caught.
