Over the past 20 years 368 gymnasts have alleged some form of sexual assault, according to an investigation conducted by the Indianapolis Star.

The report contains details about various forms of sexual abuse against gymnasts at the hands of coaches, gym owners and other adults working in gymnastics in the U.S.

The nine-month investigation concluded that coaches found to have committed abuse were allowed to move from gym to gym, and that USA Gymnastics often turned a blind eye to the horrific infractions.

The report claims that USA Gymnastics was negligent in its tracking of predatory coaches, who sometimes went without any form of punishment:

Though the vast majority of officials put children's well-being ahead of business and competition, some officials at every level have not. Coaches suspected of abuse kept their jobs as long as they accepted special monitoring. Others were allowed to finish their season before being fired. In 2009, Doug Boger was named a USA Gymnastics Coach of the Year and was sent to international competition while under investigation for alleged sexual abuse.

In August, USA Gymnastics hired a former prosecutor to provide advice on how to strengthen its policies, and established a policy review panel.

"USA Gymnastics is proud of the work it has done to address and guard against child sexual abuse," the organization said in materials provided to the Indianapolis Star.
