Cedar Hill High student in custody after school shooting threats pop up on Instagram

Cedar Hill, TX - A 16-year-old student is in custody after Cedar Hill ISD police determined he was behind a social-media threat to shoot up Cedar Hill High School.

Students returned to class amid extra security Friday after two threats appeared on Instagram Thursday night.

The school district's police force discovered a post that showed a young man making obscene gestures above a caption that partially reads, "don't go to school tomorrow I'm shooting up the school and people will die be ready ..."

Another post includes similar language and has photos of several people, many of whom appear to be students.

Both posts have been taken down.

Last night Cedar Hill Police Department notified Cedar Hill ISD Police of a school shooting threat made to CHHS. They identified the location of where it originated and have a plan to apprehend those they believe are involved. Extra security will be on duty at CHHS.

School district police alerted the city's Police Department, which quickly pinned down the source of the threat, said Jamie Brown, the district's executive director of communications.

Cedar Hill police referred all questions to the school district.

"We provided assistance overnight in the identification of those involved and are providing additional officers at several schools as a precautionary measure only," Cedar Hill police Lt. Colin Chenault said.

Thank you to the officers who worked quickly to identify the location. CHISD takes these matters seriously. Those responsible will receive consequences. Parents, talk to your children about safety. If they see something, they should say something. We value your partnership.

The district announced the arrest in a tweet just after 11 a.m. Friday. 

The suspect, who was arrested by school police and faces a felony charge of making a terroristic threat, was not identified because he is a juvenile.

A tweet sent out by the district early Friday thanked police officers for their quick actions and urged open lines of communication between parents and students.

"Parents, talk to your children about safety. If they see something, they should say something," the tweet read, adding that those responsible for the threats "will receive consequences."
