The Union County Sheriff’s Office (UCSO) took two students into custody Friday morning for making a threat to Lake Butler Elementary School.

According to a UCSO release, the Union County School District informed UCSO of a voicemail threat left by a student at the elementary school.

After an investigation, UCSO deputies apprehended a middle school student and an elementary school student before school on Friday morning.

According to the release, both students were charged with a felony crime.

This past week, several schools in North Central Florida received threats. The Columbia County Sheriff’s Office held a press conference on Wednesday after three straight days of arrests. On Sunday, a 13-year-old Madison County boy was arrested for making threats to Columbia and Madison county schools, and then a 17-year-old boy and 14-year-old girl were apprehended on Monday and Tuesday for making threats to Fort White High School.

Also on Wednesday, Chiefland schools were put on “secure campus” status while law enforcement investigated a potential threat, which later was determined to be unfounded.
