Police have arrested two students after several threats were made on social media against schools in Miami-Dade County.
The district announced the arrests Monday, saying they came after an investigation involving "several schools."
The students, a 16-year-old girl and a 15-year-old boy, face felony charges of written threats to kill or do bodily harm.

The parents of the 15-year-old said in an interview Monday night that their son was hacked and is innocent.
"We did not expect that this situation was going to get out of hand, as it did," the father said. "We saw it as one more hack, of any Facebook account or Instagram. The truth is that the police took this as a very serious crime."
Officials said police have been investigating more than a dozen threats since last week, though they said none appear to be credible.
Officials did not say what schools were threatened, but added additional police presence would be in place at several schools in the district.
