The director of a Christian boot camp and an employee were arrested Friday for allegedly dragging a 15-year-old girl behind a van after she fell behind the group during a morning run, authorities said.

Charles Eugene Flowers and Stephanie Bassitt of San Antonio-based Love Demonstrated Ministries, a 32-day boot camp, were arrested on aggravated assault charges for the alleged June 12 incident.

The two are accused of tying the girl to the van with a rope then dragging her, according to an arrest affidavit filed Wednesday by the Nueces County Sheriff's Department.

Both remained in Nueces County Jail late Friday on $100,000 bond each.

A call to Love Demonstrated Ministries was not immediately returned Friday. No listing was found for Bassitt. An answering machine at a listing for Flowers cut off during an attempt to leave a message Friday.

Flowers, the camp's director, allegedly ordered Bassitt to run alongside the girl after she fell behind, the affidavit said. When the girl stopped running, Bassitt allegedly yelled at her and pinned her to the ground while Flowers tied the rope to her, according to the affidavit.

The girl's mother gave investigators photos of her daughter's injuries that were taken at a hospital where the girl was treated and a sworn statement from a witness who claimed to see the girl being dragged on her stomach at least three times.
