RESERVE — A 15-year-old local student was arrested Friday after authorities said the male teenager threatened to blow up a school bus and a St. John the Baptist Parish Sheriff’s Office patrol unit.

The LaPlace resident was booked Friday with terrorizing and released to the custody of his mother on the same day, authorities said.

Police said the St. John Alternative School student told a school bus driver as she was driving Friday morning that he was going to blow up her bus, as well as a resource officer’s police vehicle.

Sheriff Mike Tregre and St. John the Baptist Parish Public Schools Superintendent Kevin George said authorities take all threats at local schools seriously, leading to investigations and arrests, if warranted.

Tregre said St. John officers have investigated a “few threats” over the past two months and have “not found any that represent an active, ongoing credible threat at any parish school.”

Tregre urges parents to talk with their children about recent school shootings and remind children not to share or spread rumors of threats on social media.

“If they see something of concern, they should bring it to the attention of an adult,” a Sheriff’s Office release said. “Also, making comments about bringing guns to school or shooting someone, even in a joking manner, could result in criminal charges for the student.”
