Walter Sasse, a former mounted patrol officer, was arrested and faces nine charges including unlawful contact with a minor, sexual assault, corruption of minors and aggravated indecent assault.
The victim rode horses at Courtesy Stables, where Sasse worked in Andorra. Police say the 20-year veteran of the Philadelphia police force had a sexual relationship with the then 15-year old girl. The alleged abuse lasted more than two years.
Courtesy Stables is a non-profit organization. The farm offers horse boarding and riding lessons, both of which Sasse managed, according to a cached copy of the website.
Sasse posted $50,000 bond. He is scheduled to appear in court on March 25.
