Actually I know someone who got a bit carried away when his missus left him and kept texting her on whatsapp, like scores a day. Badmouthing her and hassling her all the time and she warned him if he didn't stop she would go to the cops and he didn't.

A copper phoned him and said look mate, stop what you are doing or we will have to lift you. He assumed it was a put up job and got worse. So the plod came and got him on a Friday night and he spent the weekend in the cells. He has a dicky tummy and migraines. Did they let him have or get any medication. Did they fuck. Lol! So yes, dont get slung in jail!
