Kefford didn't say whether the person arrested was an MSD student.
"I want to thank everyone for their roles in safely resolving this situation," Kefford's message said. "I also want to remind all students and families how seriously any and all threats are taken. Parents, please speak with your children to remind them that any threat - even if they think it is a joke - will result in serious consequences."
The Parkland school was the scene of a Feb. 14, 2018 shooting that claimed the lives of 17 people.
