A star of "The Walking Dead" who also appeared in hit TV show "The Wire" and the movie "Horrible Bosses" apparently became enraged on a subway in New York City Friday over an alleged racial slur aimed at him, according to TMZ.



TMZ obtained video of the fracas, which the site says shows actor Chad Coleman screaming on the train, demanding to know "where my humanitarians are" as he reminds everyone in the car which hit TV shows he's been on.

Coleman issued an apology for his actions Saturday morning through TMZ. He told TMZ that he couldn't control his emotions because he harbored "built up frustration" over recent events in Baltimore.

In the nearly 4-minute TMZ video, TMZ says Coleman goes on a largely nonsensical profanity-laced rant about humanity and the truth, screaming, "My name is Chad L. Coleman!"

He calls someone a fool, though it's not clear who or why, and keeps screaming as riders move away from him and people in security shirts board the train, according to the TMZ video, which has no context about what preceded the rant.

Coleman, known for his roles of "Tyreese" in "The Walking Dead" and "Cutty" in "The Wire," told TMZ he was upset because a woman asked a man she was with if they knew the actor and the man used a racial slur when telling her they did not know him.

He told the website he was screaming about humanity in response to the unrest in Baltimore following the death of Freddie Gray. Authorities said this week his death was a homicide, and six police officers have been charged, one of them with murder.

A call to Coleman's booking agency wasn't immediately returned.
