NBC New York:

Alec Baldwin has been arrested in New York after he was allegedly riding the wrong way down a Manhattan street on his bike and argued with police who tried to ticket him, NBC 4 New York has learned.

A law enforcement source says Baldwin was seen riding his bike the wrong way down a street in the Flatiron district Tuesday morning and when police stopped to give him a summons, he grew angry.

Baldwin 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.

Baldwin could not immediately be reached for comment. He was at the precinct Tuesday morning.
