Sheriff Jack Strain and others survey the scene inside Lakeshore High School, which was briefly placed on lockdown Friday.

For the second time in as many days, law enforcement officers were summoned to a St. Tammany Parish high school. And again, the potential threat turned out to present no danger to the school, students or faculty.

Thursday, officers from Mandeville Police went to Mandeville High School to investigate rumors of a potential shooting threat. It turned out that a student’s innocent comment — overheard and misconstrued — had sparked the fears. Nothing happened and no one was punished.

Friday, Lakeshore High School was briefly placed on lockdown after a man phoned the St. Tammany Parish Sheriff’s Office and asked for an escort to the Mississippi state line because he was being pursued by “witches and demons,” according to St. Tammany Parish Sheriff’s spokeswoman Suzanne Carboni.

The man told a 911 operator that he was on La. 1088 near the high school and that he had some knives and a bulletproof vest.

The operator informed Sheriff’s deputies, who dispatched several units to the high school to set up a perimeter. In addition, Sheriff Jack Strain called School Superintendent Trey Folse and let him know what was happening. As a precaution, the school was placed on lockdown, Carboni said.

Soon after the 911 call, deputies learned the man had continued into Mississippi on Interstate 12. Authorities in that state were notified, and the lockdown was lifted, Carboni said.
