NBC affiliate WTHR reported that the investigation began with a complaint from a female gymnast at Sharp’s Gymnastics Academy. On Sunday evening, detectives searching for child pornography removed computers and other electronic devices from Sharp’s home, the station reported.

In a statement, USA Gymnastics told WTHR that it “is cooperating with law enforcement's active investigation” of Sharp.

According to the academy’s website, Sharp opened the facility 14 years ago and has sent over 100 athletes to national championships.

In 2008, Sharp's gymnasts participated in the academy’s first Olympic games. According to WTHR, two of them, Samantha Peszek and Bridget Sloan, won silver medals in Beijing.
