Multiple Oklahoma schools have received threats of violence that have sent them into lockdown this week, the Tulsa World reports.
"Bixby Public Schools are on lockdown Friday in addition to a Muskogee junior high school where two students were arrested after a gun was found in their possession earlier this week.
Someone sent a social media post to Bixby police officers after it was posted just before midnight. Bixby Police Cpl. Michael Konshak said the Instagram post was timestamped 11:58 p.m. Thursday.
The threat, he said, was posted under the moniker "schoolshooters6969" and only stated 'Union, then to Bixby.'"
Oklahoma City schools received at least four violent threats last week in the immediate aftermath of a school shooting in Parkland, Florida, that killed 17 people.
