One day after the Parkland, Florida school shooting, an 11-year-old was arrested for writing a letter saying she was planning to kill people at her Florida middle school, WPLG-TV reported. The child, who attends Nova Middle School, can be seen on surveillance footage, leaving a note under the door of the assistant principal office. Police have not released the footage.

An 11-year-old girl has been arrested for writing a note threatening to shoot students and staff at her school just one day after a gunman stormed a Florida high school and killed 17 people."I will bring a gun to school to kill all of you ugly a** kids and teachers b****,"

The girl’s note reads: “I will bring a gun to school to kill all of you ugly a-- kids and teachers b---h. I will bring the gun Feb, 16, 18. Be prepared b---h!” The girl has been taken to Broward Juvenile Assessment Center. As WPLG-TV reports, the girl told police that she herself was threatened by a classmate to write the letter. She says the classmate would get another student to attack her if she didn’t comply. The girl also said that the other student threatened her over a boy.

The police have released a handwritten confession from the girl. It reads, “I placed a note under the AP door and I got caught on tape." It continues, "My friend Sarai to write the letter or she will get her friend to fight me because she does not like because someone said that I like (name withheld). So to avoid getting in a fight with her friend, I put the letter under the door." 

Nova Middle School is about half an hour away from Marjory Stoneman Douglas High School in Parkland, where 19-year-old suspect Nikolas Cruz allegedly killed 17 people on Wednesday.
