Threat-tweeting teen free after hearing

The Dutch teenager, Sarah, who tweeted a fake threat to American Airlines is free again after a hearing in Rotterdam, the police reports. She remains a suspect, however. 

Sarah's tweet has fueled a barrage of threat tweets to the airline, as well as the Rotterdam police. "Let her go or I will blow up your headquarters. Will you arrest me now?" asks someone who calls themselves admrl.anonymous and tweets with the account @nonfreak.

The tweeter questions whether @Politie_Rdam wouldn't rather catch thieves rather than innocent teenagers. "I mean, it's obvious that this was a joke."

Sarah announced herself at a police station in Rotterdam after American Airlines told her that they sent her information to the FBI.

Other tweeters, even those abroad, have been sending American Airlines similar 'joke' threats, referring to themselves as terrorists.
