(KCEN) -- A Dallas-area high school student is in jail after he posted a threatening statement on Facebook last night.
The teen was arrested around 9:30 in McKinney.
That's after the McKinney School District told police about the Facebook post, which included details on how to carry out a mass shooting at the school.
There are reports the student may have been bullied.
His name is not being released because he is a minor.
