(CNN) -- Police arrested a 14-year-old Dutch girl Monday after she tweeted a terror threat to American Airlines that catapulted her into social media fame overnight.

A Twitter user calling herself Sarah with the handle @QueenDemetriax_ tweeted
"@AmericanAir 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 Airlines responded swiftly from their official Twitter account saying "@QueenDemetriax_ Sarah, we take these threats very seriously. Your IP address and details will be forwarded to security and the FBI."

Moments later, in a series of tweets, the girl pleaded with the airline, writing "I'm just a girl" and claiming the threat was a joke made by her friend.

The teenager turned herself in at a police station in the Dutch port city of Rotterdam on Monday afternoon after authorities launched an investigation into her whereabouts, Wessel Stolle, a Rotterdam police department spokesman told CNN.
