A teacher at Donelson Christian Academy is on indefinite leave after the administration learned Metro Nashville's Sex Crimes Unit is investigating him for alleged inappropriate behavior.
The allegations came to light over the weekend and DCA officials said they notified parents via email.
According to the school's Web site, David Turner teaches elementary Spanish and computers at the private school.
Since the investigation is open, authorities are unable to share additional details.
School Director of Advancement Matthew Work released a statement Wednesday afternoon which read, "We have been proactive in addressing this issue but are limited in what we can say to be supportive of the process and people involved."
The statement continued, "We hope all members of the community will exercise discretion when discussing this topic to be respectful to all parties involved. Ultimately, our students' welfare and best interest remain our top priority. We will continue to communicate as is appropriate in accordance with directives given to the school."
Authorities would only confirm that the sex crime unit is investigating the allegations involving Turner and he is no longer in the school setting.
Metro police spokesman Don Aaron would not comment on specifics of the investigation nor comment on how long it could take.
It is unclear if the allegations against Turner involve behavior related to current students or acts that took place on the DCA campus.
Parents at DCA declined to comment about the allegations as well aside from one parent telling Nashville's News 2 that she was notified about the allegations via an e-mail the school.
Turner's biography on the DCA Web site said he is in his sixth season as the head varsity coach for both the boys' and girls' bowling teams.
Throughout his time as a coach, Turner has led both teams to the state tournament and coached several DCA students to participate in the TSSAA Individual State Tournament.
