A 14-year-old Dutch girl was arrested a day after foolishly tweeting a terrorism joke at American Airlines. The arrest was confirmed by Rotterdam police.

The girl, Sarah, told American Airlines, "hello my name's Ibrahim and I'm from Afghanistan. I'm part of Al Qaida and on June 1st I'm gonna do something really big bye." American's Twitter account responded by promising to forward her information to the FBI. They were not joking, it seems.

Below, our original story on the exchange, featuring Sarah's very teenage-girl freakout.
