Alec Baldwin has been accused of unleashing a racist rant against a paparazzi photographer outside his apartment building.
The 30 Rock star found retired New York Police Detective G. N. Miller staking his Manhattan home on the weekend trying to gain information on Baldwin's pregnant wife, yoga teacher Hilaria Thomas - who is being sued by a student.
Baldwin is alleged to have called Miller, who is black, a "coon" and a "crackhead" and unleashed other insults before making comments about his mother, the former police officer wrote in his statement.
The 54-year-old actor also apparently told the snapper to "suck my d***" and branded Miller's ID showing he is a retired police officer as "fake".
Miller told the New York Post newspaper: "He was saying some serious racist stuff. He could have said a lot of other stuff. But he used all of the stereotypes associated with black people."
Shortly before the altercation, Baldwin had been approached by a female New York Post reporter inquiring about the lawsuit against his wife, to which Baldwin is said to have responded by grabbing her arm and saying: "I want you to choke to death."
Baldwin is filing a formal complaint against Miller - who he refers to as "Ralston" in a series of tweets.
In a post now deleted, Baldwin wrote on Twitter: "Moments after I tweet about the Post, Ralston, the ex-crackhead "photographer" shows up at my door w 1 of Murdoch's nieces in tow.
"Ralston claims he's ex NYPD!! That can't be!!! Ex NYPD don't become crackhead, ex jailhouse paparazzi! (sic)"
He also thanked officers who came to his home and took his statement about being "assaulted".
He continued in tweets that still remain on his page: "Thank u 2 NYPD officers who came to my home 2day so that I could file a formal complaint against NY Post "photographer" who assaulted me (sic)"
Baldwin told police Miller "pushed into him", but the photographer claims it was the other way round.
In a statement on behalf of the actor, a spokesperson said: "That's one of the most outrageous things I've heard in my life."
Baldwin, 54, told Gothamist: "This guy was right up in my face as I crossed University Place. I get to the other side of the street, and he bumped into me.
"He banged into me with his shoulder, because he was right on top of me with the camera. In my mind, it was deliberate. I've had that happen before. It happens sometimes, because they want to bait you, they want you to do something.
"My wife is pregnant and I'm trying to make sure she has as much peace as possible. Who knows what these people can do?
"While police were here, you'd figure that'd be an opportune time for this guy to really attempt to tar me in some way. But there was no mention of anything I said to him. No one said anything about me saying the n-word or taunting him or anything. So it was after the fact. He wants to say I used some racial slur against him."
