A 16-year-old girl has been arrested in a series of social media threats against students and teachers at Linden High School that prompted an hours-long lockdown and an early dismissal at the school Tuesday, authorities say.
The girl allegedly created an Instagram account called "lhslasthours," and posted a series of photos to it on Tuesday, Union County prosecutors say, including one depicting a rifle resting on a car's steering wheel with the caption, "11:36 AM."
Additional captions on other posts on the same account threatened that the author would be "shooting anyone who gets in my way" and warned "do all your little drills, I'm already in the building."
Linden High School was put on lockdown for more than four hours Tuesday as police responded and investigated. Students reported sitting on the floor waiting during the lockdown hours.
No threat was found in the school, but students were dismissed for the day shortly after 1 p.m.

The girl is not being identified due to her age.
