Tennessee Code Title 49. Education § 49-6-4105

(a) No action taken by a teacher or principal pursuant to this part shall be grounds for the issuance of an arrest warrant or for the pressing of criminal charges against the teacher or principal, unless a report of an investigation by appropriate law enforcement officials along with independent medical verification of injury is presented to the judge or magistrate prior to issuing the warrant. The investigative findings shall be presented to the judge or magistrate within fifteen (15) days of receipt of notification. The law enforcement agency shall give notice to the director of schools or the director of schools' designee at the time it is notified of the allegations.

(b) When an arrest warrant has been issued against a teacher for action taken pursuant to this part, the teacher shall be summoned to an administrative office or to a location other than on school grounds, so that students shall not be present, and shall be arrested there. The teacher is not to be arrested in the classroom or before any assembly of students. This subsection (b) shall not apply if a law enforcement officer reasonably believes that the teacher will flee from arrest or attempt to leave the jurisdiction of the court that issued the warrant.
