Police in Rotterdam, Netherlands, confirmed to NBC News that a 14-year-old girl has been arrested in the Netherlands for allegedly writing a message on Twitter that threatened American Airlines.
The original tweet has since been deleted, however various news organization have reported the exchange between the teen, who tweeted under a fake name, and the airline's customer service Twitter handle.
The message from @QueenDemetriax_ reportedly said "@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"
The latest news from around North Texas.
The airline responded through their @AmericanAir account. "@queendemetriax_Sarah, we take these threats very seriously. Your IP address and details will be forwarded to security and the FBI."
Rotterdam police said they first heard of the tweet when a member of the public notified authorities. According to police, they investigated the information on their own without a request from authorities in the U.S.
"It was a serious tweet, so we had to investigate," a spokesperson told NBC News.
Once police investigated and discovered the identity of the person behind the alleged tweet, that teen and her mother went to the police station to turn the teen over to authorities. Authorities are questioning the girl, but have not yet filed charges.
When asked for comment, American Airlines representatives said "At American, the safety of our passengers and crew is out top priority. We take security matters very seriously."
Meanwhile others, including the teen alleged to be behind the tweet, said the message sent to the airline was a "joke."
