A couple of years ago I was back in my home town in Ireland, just outside of Dublin.
The local paper there is called the Liffey Valley Champion and there was an article about this exact same thing happening in a playground in the town of Maynooth.
Seemingly the same person may also have been pooing into golf holes, so when you’d pick the ball out, you’d get poo all over you hands, I believe the Police were going to DNA type both shites and see if it was the same person.
Maybe its a thing?
