Detectives were made aware of the alleged violations late Monday afternoon by the Putnam County Department of Child Services, which had received a tip about the alleged sexual activity.
Officers arrested Michael E. Fife, 20, Reelsville. Fife was preliminarily charged with Sexual Misconduct with a Minor (a class C felony), and Disseminating Obscene Matter or Performance to a Minor (a class D felony).
According to officials, during the past year to year-and-a-half time period -- and beginning when the victim was 14 -- Fife was alleged to have had sexual relations with the minor on multiple occasions.
The incidents allegedly occurred at various locations in Putnam County. On one alleged occasion, the victim was alleged to have witnessed a sexual encounter involving other adults.
Fife was arrested without incident and incarcerated in the Putnam County Jail, with no bond.
According to ISP officials, the investigation is ongoing and additional arrests may take place.
