He later tweeted that "New York City is a mismanaged carnival of stupidity that is desperate for revenue and anxious to criminalize behavior once thought benign."
A law enforcement source said Baldwin was seen riding his bike the wrong way in the Flatiron district near 16th Street Tuesday morning and when police stopped to give him a summons, he grew angry.
Baldwin, who was wearing a black jacket, black shorts and a black visor, was not carrying ID, the source said. When police are handing out a summons to someone who has no ID, they bring the person to the police station.
He was issued two summonses, one for riding his bike the wrong way and another for disorderly conduct, an NYPD spokesman said.
Baldwin tweeted that "police did nothing" when photographers nearly hit his daughter with a camera outside his home later in the day.
