Lincolnshire Police arrested a man who indecently exposed himself in front of a 13-year-old girl in Lincoln.
The incident occurred in the Bailgate area of Lincoln on the morning of September 4.
Police attended the scene and located and arrested a 69-year-old man.
It is thought that the man could have approached other people in the area, so police would like to know if he engaged in any other inappropriate sexual behaviour in or around the Bailgate on the same day, or days beforehand.
Anyone with information contact P.C. Scott Chapman on 101, quoting incident number 90 of 4th September 2012.
