NASHVILLE, Tenn. (WKRN) — Metro police are investigating a threat Wednesday morning at Martin Luther King Jr. High School near downtown Nashville.

Multiple officers responded to the school on 17th Avenue North around 8:40 a.m.

The school was placed on lockdown while officers canvassed the building to investigate, according to the principal.

A spokesperson for Metro Nashville Public Schools said a call was placed to the school threatening violence. Officers determined the call to be a hoax and continued to search all the rooms out of an abundance of caution.

MLK reported the building has been cleared and all students are safe.

The school requested students to remain in class, if possible, but parents are asked to pick up their students at nearby Watkins Park. Parents who responded to the school to pick up students have signed release forms to retrieve their children.

The lockdown will be lifted once all students who need early dismissal have been released to their parents, according to MNPS.

School will dismiss at its regularly scheduled time.

Metro police reported they are working closely with the Federal Bureau of Investigation after multiple unfounded threats to places in Nashville beginning last Thursday. Threats were placed against the Nashville International Airport, a police precinct, the Hard Rock Café downtown, the AT&T building downtown and Hunters Lane High School in addition to MLK.

Investigators believe the likelihood that these specific telephoned threats are originating from outside Tennessee as there have been hundreds of similar threats in other American cities as well as those outside the United States.

Metro police said the department is taking all threats of harm seriously and is taking appropriate action in the midst of the hoax calls that have been received since late last week.

No additional information was immediately released.
