The actor Alec Baldwin, who won an Emmy for mocking President Trump on “Saturday Night Live,” was taken into custody outside his Manhattan apartment building on Friday after getting into a dispute about a parking space, the police said.

Mr. Baldwin was issued a summons for misdemeanor assault and harassment.

The police said that someone was apparently holding a parking space for Mr. Baldwin, 60, outside his building on East 10th Street between University Place and Broadway, but that another car pulled into the space. The police said the other driver, 49, and Mr. Baldwin got into an altercation.

Officers who responded to a 911 call found that the other driver, who was not identified, had an injury to his jaw. He was taken to Lenox Hill Hospital and was listed in stable condition. Jillian Taratunio, a publicist for Mr. Baldwin, said she had no comment on the incident.

Mr. Baldwin has portrayed President Trump on “Saturday Night Live” with a custom-made wig, glued-on eyebrows and puckered lips. He and the president have sparred on social media from time to time.
