Police stopped ALEC BALDWIN for illegally riding his bike against traffic down a New York City street yesterday.  And to the surprise of NO ONE, he proceeded to throw a huge tantrum, which resulted in him being taken into custody.



In a Twitter rant, Alec said, quote, "Officer Moreno, badge number 23388, arrested me and handcuffed me for going the wrong way on Fifth Ave . . .  Claims by Moreno of disorderly conduct are either a distortion or outright lie.  Moreno lied in her report. 



"Handcuffing someone for riding a bicycle in the wrong direction is ridiculous.  New York City is a mismanaged carnival of stupidity that's desperate for revenue and anxious to criminalize behavior once thought benign.



"Meanwhile, photographers outside my home ONCE AGAIN terrified my daughter and nearly hit her with a camera.  The police did nothing."



(In most of his Tweets, Baldwin mistakenly called the guy Moreno, but he later corrected himself and said the arresting officer's name was actually Montero.)



Alec was reportedly arrested and handcuffed because he was acting "belligerent."  He was detained, in part, because he wasn't carrying any I.D. at the time . . . and a "source" says he yelled, quote, "[Eff] this.  This is horse[crap].  Don't you know who I am?"



He was issued a court summons, fined, charged with disorderly conduct, and released.
