Law enforcement sources told the network that he punched the person in the West Village neighborhood.
Other details were not available.
The man apparently swooped in on the parking spot that Baldwin, who lives in the area, was going to take, leading to the altercation and arrest, the report stated.
Baldwin, who portrays President Donald Trump on “SNL,” also yelled a profane comment during the alleged melee.
After the news of Baldwin’s arrest broke out, President Trump said: “I wish him luck” when reporters asked, NBC reported.
“Don’t you know my taxes pay your salary?” he screamed at the time, the Post reported. Baldwin was “totally belligerent” during the incident. “How old are these officers?” he also allegedly stated at the time. “They don’t even know who I am.”
“New York City is a mismanaged carnival of stupidity that is desperate for revenue and anxious to criminalize behavior once thought benign,” Baldwin tweeted after the incident.
In the 1990s, Baldwin was acquitted of battery in a case involving a photographer.
