Sean Gardner, a former gymnastics coach at Chow’s Gymnastics and Dance Institute in West Des Moines, Iowa, has been arrested on child pornography charges.

The US gymnastics world was only just recovering from a devastating sexual abuse scandal when a promising young coach moved from Mississippi to Iowa to take a job in 2018 at an elite academy known for training Olympic champions.

Sean Gardner is facing federal charges for child pornography, alleging he used a hidden camera to record underage gymnasts in Mississippi.
