PECULIAR, Mo. -- A student in the Raymore Peculiar School District is in police custody, accused of making false threats of a possible attack Thursday at Ray-Pec High School.
There's additional police officers providing security at the school.
Raymore police told FOX 4 News the adult male student is being held in the Cass County Jail. The Cass County Prosecutor is expected to make a decision on criminal charges by the end of Thursday, May 1.
Parents and staff alerted school leaders to a threat posted on a Facebook Wednesday. The school district started investigating and immediately got police involved. News of the Facebook post spread like wildfire on Twitter, with messages claiming there's going to be a shooting at the south school building or bombs all around campus.
Raymore police interviewed the student they believe is responsible for the original post and took him into custody. Both police and school officials say that based on their investigations, they don't believe the threat was credible, but they also are not taking anything for granted.
"It's really hard to know what the details or the motivation might be in a situation like that," said Kari Monsees, school superintendent. "You rely on your investigation and your cooperation with law enforcement authorities to help determine what the truth might be. In this case, we believe there was never any real threat to our students or our staff members."
Extra police patrols are taking place at all schools in the district to calm any remaining fears. Both school leaders and police say parents are thankful for the swift response to the threat and for the extra security in place. Police say no threat can be taken too seriously.
"I think the kids need to understand that there are consequences to the things they post on social media," said Raymore Police Capt. Roger Mayberry. "There are people looking and checking up on them."
The Cass County Prosecutor's office tells FOX 4 News they haven't received the case file yet. Prosecutors will need time to review it before determining if criminal charges are warranted. That may not happen until later this evening. FOX 4 News is not identifying the student unless or until criminal charges are filed.
