Hot-headed actor Alec Baldwin was busted and cuffed Tuesday morning after riding his bicycle the wrong way up Fifth Avenue and then swearing at two female cops who pulled him over -- later griping, "How old are these officers? They don't know who I am?"

Baldwin blew his top at the cops when they questioned him, the sources said. "He became belligerent, yelling and screaming at the officers: 'I don't have ID. Just give me the fucking summonses,'" a source said.

Because of his bad attitude and lack of ID, the cops handcuffed him and brought him to the 13th Precinct station house for a warrant check, sources said.

"Officer Moreno, badge number 23388, arrested me and handcuffed me for going the wrong way on Fifth Ave" ... "Meanwhile, photographers outside my home ONCE AGAIN terrified my daughter and nearly hit her with a camera. The police did nothing" ... "New York City is a mismanaged carnival of stupidity that is desperate for revenue and anxious to criminalize behavior once thought benign."
