A gym teacher at a private Christian school in Florida was arrested after his explicit text messages to a 14-year-old girl were found by her mother, authorities said.

Stephen Ward — a 69-year-old physical education teacher and volleyball coach at Stetson Baptist Christian School in DeLand — was arrested Saturday after the teen’s mother found the texts and notified deputies with the Volusia County Sheriff’s Office, the Orlando Sentinel reports.

The text messages detailed Ward performing sex acts on the girl, who told deputies she “has been in a relationship” with Ward for roughly two weeks, but denied having sexual contact with him, according to the Sentinel.

WMKG reports that Dan Glenn, a pastor at Stetson Baptist Church, acknowledged Sunday in a statement via its website that Ward was accused of “attempting to begin an improper relationship with a minor,” adding that he had been placed on administrative leave. School staffers are also cooperating with law enforcement officials in the ongoing investigation, he said.

“In the meantime, as a church, our thoughts and prayers are with everyone involved in this situation, especially the young woman involved and her family,” Glenn said.

Ward remained held on $10,000 bail as of Monday on charges of using a computer to lure a child and unlawful use of a two-way communication device, jail records show.

The Volusia County Sheriff’s Office asks any other potential victims to contact them at (386) 323-3574.
