18-year-old student arrested for school threat causing panic in Broward and Miami-Dade districts.

An 18-year-old student at Taravella High School in Coral Springs, Florida, has been arrested for allegedly transmitting a school shooting threat using another student's name and computer access. The threat sparked panic in several districts, including Broward and Miami-Dade, before being deemed non-credible. The student is facing multiple felonies, and the incident has prompted increased security measures in schools across the state. Non-credible threats have been reported in several other districts, and Broward Public Schools has announced that all students will have to bring clear backpacks and bags in the fall.
