What did he do or say this time?

Alec Baldwin was arrested in New York City this morning, In Touch reports.

The magazine acquired pictures of the actor being handcuffed and put in the back of a cop car by an officer. Although one witness described the 30 Rock star as "calm and quiet" during the arrest, another said he "went ballistic on the cops, screaming at them" while being taken away.

"The incident just happened, we are waiting for details at this time," an NYPD source told the glossy.

Update: Baldwin was cited for illegal biking after going the wrong way on Fifth Avenue, and a factor in the arrest was that he didn't have his ID on him while he was riding, TMZ reports.
