The Ronald W. Reagan/Doral Senior High School, located at 8600 NW 107 Avenue in Doral, was likewise the subject of a purported threat. Lockdown was also imposed on the school.

The county’s education district claimed to have received calls relating to the schools and a few others and was able to verify that there was in fact no threat.

“It appears to be a hoax. We’re getting the same threat at different schools,” Miami-Dade schools police Chief Edwin Lopez said. 

They may have been swatting calls, in which a caller reported a threat at a particular location when none actually existed.
