It happened around 1:50 p.m. on Aug. 15th, inside the Goodwill Store on the 200 block of East Main Street.
Authorities say a 6-year-old girl reported that an unknown male approached her while she waited for her mother outside the dressing room.
The child told police that the suspect pulled down his pants and exposed himself to her.
The little girl called for her mother and the suspect fled the store.
Police describe the suspect as a white male, 5'7" tall 180-195 pounds with dirty blond, shoulder length hair. He was wearing a blue shirt with black stripes and black pants.
