Law enforcement officials investigated threats Monday at one school in Ascension Parish and two in Tangipahoa Parish, including one in which an Amite High School student threatened to shoot students and teachers.

The 18-year-old student at Amite High School threatened to shoot students and faculty at the high school, according to the Tangipahoa Parish Sheriff's Office.

Troy Webber, was arrested Monday and booked on a terrorizing count after deputies determined the threat was "credible," a news release from the Sheriff's Office says.

"Webber was overheard by other students making verbal threats. When approached by deputies, he confessed that he indeed made the threats, however, he had no intentions of acting on them," Tangipahoa Parish Sheriff's Office spokeswoman Dawn Panepinto said in an email.

The Sheriff's Office also investigated a second threat shared on social media Monday night relating to Ponchatoula High School that turned out to be unfounded.

A juvenile student shared a post of Snapchat Sunday night that said a school shooting would happen on Monday. Rumors of the post — which turned out to be in reference to an out-of-state school — caused "fear and panic among our community members," the news release says.

The juvenile student who shared the post is facing charges of terrorizing, according to the news release. The 17-year-old who provided the post to the juvenile was arrested on charges of contributing to the delinquency of a minor, the release says.

In a third incident, Ascension Parish Sheriff’s Chief Deputy Bobby Webre said a former Dutchtown High School student now living in Texas made a social media threat Sunday evening that named the high school.

The social media threat started as a “picking a fight against each other” type of post between two individuals, with language that escalated, Webre said.

"We do not have reason to believe there is imminent danger to Dutchtown High School or any of our schools. The Sheriff’s Office will continue its investigation and is confident that our schools will be well protected each day, and students will remain safe," a statement from the Ascension Parish school district said. 

Law enforcement in Texas has contacted the former Dutchtown student and his parents, Webre said.

Law enforcement continues to have an increased presence at schools in both districts.
